Too many greenhouse gasses in the atmosphere may block heat from escaping into space and trap too much heat next to the Earth’s surface causing: global warming. *
What is global warming?The human activities produce greenhouse gases such as carbon dioxide, carbon monoxide, methane, nitrogen oxides and others gases.
These gases when enter into the atmosphere because of their diatomic structure are capable of trapping the light energy from sun.
The abundance of these gases in the air is making the global temperature warm, which chiefly responsible for drought like conditions and melting of glaciers in some locations.
Then The trapped sunlight cannot be reflected back to the space this phenomena is called as greenhouse effect and the phenomena of increase in global temperature is called as global warming.

A satellite is at the end of its serviceable life. It I moved to an orbit of 49870 km from the earth . What is its time period,velocity and acceleration
Answer:
Explanation:
Assuming the satellite is in a circular orbit, we can use the following equations to calculate its time period, velocity, and acceleration:
Time period (T): T = 2π√(a^3/GM), where a is the radius of the orbit, G is the gravitational constant, and M is the mass of the Earth.
Velocity (v): v = √(GM/a), where G is the gravitational constant, M is the mass of the Earth, and a is the radius of the orbit.
Acceleration (a): a = v^2/a, where v is the velocity and a is the radius of the orbit.
Using the given radius of the orbit (a = 49870 km = 4.987 x 10^7 m) and the known values of G and M, we can calculate the time period, velocity, and acceleration as follows:
Time period: T = 2π√(a^3/GM) = 2π√((4.987 x 10^7)^3/(6.674 x 10^-11 x 5.972 x 10^24)) = 85514 seconds.
Therefore, the time period of the satellite is approximately 23.75 hours (85514 seconds / 3600 seconds per hour).
Velocity: v = √(GM/a) = √((6.674 x 10^-11 x 5.972 x 10^24)/(4.987 x 10^7)) = 3074.4 m/s.
Therefore, the velocity of the satellite is approximately 3074.4 m/s.
Acceleration: a = v^2/a = (3074.4 m/s)^2/4.987 x 10^7 m = 0.190 m/s^2.
Therefore, the acceleration of the satellite is approximately 0.190 m/s^2.
The velocity of a body change from vi to 30m/in 20econd if the rate of change of velocity i 4m/2 find vi
The velocity of a body change from vi to 30m/s in 20econd if the rate of change of velocity is 4m/s, initial velocity is -50 m/s.
To find the initial velocity, vi, of a body that undergoes a change in velocity, you can use the formula:
vi = vf - at
where vi is the initial velocity, vf is the final velocity, a is the acceleration (rate of change of velocity), and t is the time over which the acceleration occurs.
In this case, you are given that the final velocity is 30 m/s, the acceleration is 4 m/s^2, and the time is 20 seconds. Plugging these values into the formula gives:
vi = 30 m/s - 4 m/s^2 * 20 s
vi = 30 m/s - 80 m/s
vi = -50 m/s
Therefore, the initial velocity of the body is -50 m/s.

Determine the kinetic energy of a 1000 kg roller coaster car that is moving with speed of 40.0 m/s
Answer:
KE=800,000
Explanation:
The formula for kinetic energy is KE=1/2mv^2 or Kinetic Energy= 0.5*mass*velocity^2
so 1000 is the mass and 40 is the velocity
KE=0.5*1000*40^2
KE=0.5*1,000*1,600
KE=800,000 Joules
A slope of length 50 m rises to a height of 10 m above the ground. An effort of 100 N is needed to push a 250 N object up the ramp. Calculate: 1. AMA 2. VR 3. efficiency
1.) The AMA is 2.5
2.) The VR is 5.
3.) The efficiency is 50%.
Given that the object has a weight of 250 N and the effort needed to push it up the ramp is 100 N, we can calculate the AMA as follows:
AMA = Load / Effort
AMA = 250 N / 100 N
AMA = 2.5
Therefore, the AMA is 2.5.
To calculate the VR, we need to find the distance moved by the effort and the distance moved by the load. The distance moved by the effort is the length of the ramp, which is 50 m. The distance moved by the load is the height it is raised, which is 10 m. Therefore, we have:
VR = Distance moved by effort / Distance moved by load
VR = 50 m / 10 m
VR = 5
Therefore, the VR is 5.
To calculate the efficiency, we need to find the work done by the load and the work done by the effort. The work done by the load is:
Work done by load = Load x Distance moved by load
Work done by load = 250 N x 10 m
Work done by load = 2,500 J
The work done by the effort is:
Work done by effort = Effort x Distance moved by effort
Work done by effort = 100 N x 50 m
Work done by effort = 5,000 J
Therefore, the efficiency is:
Efficiency = (Load x Distance moved by load) / (Effort x Distance moved by effort)
Efficiency = (2,500 J) / (5,000 J)
Efficiency = 0.5 or 50%
Therefore, the efficiency is 50%.

l'hopital's pulley problem show that when the system reaches equilibrium the value of x is
The L'Hospital's rule states that if two functions tend to the same limit, then their derivatives also tend to the same limit. In the case of the pulley problem, when the system reaches equilibrium, the value of x is the limit of the ratio of the forces acting on the pulley.
To solve this problem, we need to use L'Hopital's Rule, which states that if the limit of the ratio of two functions f(x) and g(x) is in the form of 0/0 or ∞/∞, then the limit of the ratio can be found by taking the derivative of both functions and finding the limit of the new ratio. In this case, we are given the equation: f(x) = g(x) Taking the derivative of both sides gives us:
f'(x) = g'(x)Now we can plug in the values for f(x) and g(x) and solve for x:
f'(x) = 2x g'(x) = 4Setting the two derivatives equal to each other and solving for x gives us:
2x = 4 x = 2Therefore, when the system reaches equilibrium, the value of x is 2.

The compass is a small bar magnet that’s free to spin. Based on what you observed, is the coil of wire with current passing through it a magnet?
Answer:
People have been aware of magnets and magnetism for thousands of years. The earliest records date back to ancient times, particularly in the region of Asia Minor called Magnesia—the name of this region is the source of words like magnet. Magnetic rocks found in Magnesia, which is now part of western Turkey, stimulated interest during ancient times. When humans first discovered magnetic rocks, they likely found that certain parts of these rocks attracted bits of iron or other magnetic rocks more strongly than other parts. These areas are called the poles of a magnet. A magnetic pole is the part of a magnet that exerts the strongest force on other magnets or magnetic material, such as iron. For example, the poles of the bar magnet shown in Figure 20.2 are where the paper clips are concentrated.
A bar magnet with paper clips attached to it.
Figure 20.2 A bar magnet with paper clips attracted to the two poles.
If a bar magnet is suspended so that it rotates freely, one pole of the magnet will always turn toward the north, with the opposite pole facing south. This discovery led to the compass, which is simply a small, elongated magnet mounted so that it can rotate freely. An example of a compass is shown Figure 20.3. The pole of the magnet that orients northward is called the north pole, and the opposite pole of the magnet is called the south pole.
Answer:
Yes, the coil of wire with current passing through it is a magnet.

Explanation:
Given that,
Force with which a child hits a ball is 350 N
Time of contact is 0.12 s
We need to find the impulse received by the ball. The impulse delivered is given by :
\(J=F\times t\\\\J=350\times 0.12\\\\J=42\ N-m\)
So, the impulse is 42 N-m..
We know that he change in momentum is also equal to the impulse delivered.
So, impulse = 42 N-m and change in momentum =42 N-m.

The right response is (a) 9.0 V. Options (b), (c), and (d) are incorrect because this computation does not take into account the angle between the two points.
The electric potential at point B can be found using the formula V = kq/r, where k is the Coulomb constant, q is the charge, and r is the distance between the point charge and point B.
In this case, the distance from point A to point B is given as 1.0 meter. Therefore, the electric potential at point B can be calculated as:
V = (9 x \(10^{9}\) Nm²/C²) x (1.0 x \(10^{-9}\) C) / (1.0 m) = 9.0 V

A major feature of the solar system is that as planets get farther away from the sun they tend to have longer orbital periods and lower surface temperatures.
This is known as the "distance-temperature relationship" in the solar system. The four inner planets (Mercury, Venus, Earth, and Mars) are relatively small and close to the sun, and they have relatively short orbital periods and high surface temperatures.
In contrast, the four outer planets (Jupiter, Saturn, Uranus, and Neptune) are much larger and farther from the sun, and they have much longer orbital periods and lower surface temperatures.
This pattern can be explained by the fact that the sun's heat and light decreases as you get farther away from it, and the larger planets have more mass to retain and distribute this heat, thus keeping their temperatures lower.

Relative velocity implies the the velocity of a given object being observed from another object. The relative velocity of rocket A relative to B is 4.38 x \(10^{7}\) m/s.
Relative velocity is the velocity of a given object with respect to a reference frame. Thus if the reference frame is another object at motion, then;
i. the velocity of A relative to B (Vab) = Va - Vb
ii. the velocity of B relative to A (Vba) = Va - Vb
In the given question, it can be deduced that:
speed of rocket a = 0.811c
where c = 3.0 x \(10^{8}\)
speed of rocket A = 0.811 x 3 x \(10^{8}\) m/s

What are the products of pyrolysis of hexane and why pentene is not one of them and i want to understand its mechanism?
Pyrolysis is a chemical process that involves the thermal decomposition of organic compounds in the absence of oxygen. When hexane, a hydrocarbon with six carbon atoms, undergoes pyrolysis, it breaks down into smaller molecules and radicals.
The products of hexane pyrolysis mainly consist of smaller hydrocarbons, such as ethylene, propylene, butenes, and various other alkanes and alkenes. These products are formed through a series of complex radical reactions, which include initiation, propagation, and termination steps.
Pentene, a hydrocarbon with five carbon atoms and one double bond, is not a major product of hexane pyrolysis, mainly because of the reaction mechanisms involved. The cleavage of C-C bonds in hexane primarily occurs at positions that result in the formation of smaller, more stable hydrocarbons, like ethylene and propylene. These stable products are favored due to their lower energy states and higher stability. The formation of pentene would require a specific bond cleavage that is less likely to occur during pyrolysis and is less favorable from an energy standpoint.
In summary, the products of hexane pyrolysis are mainly smaller hydrocarbons, and pentene is not a significant product due to the reaction mechanisms and energy considerations that favor the formation of more stable molecules.
