Volcanism can be studied to found out evidence of the internal structure of the Earth.

Answer:

Volcanism

Explanation:

The force that is acting between the earth and the satellite is  1.49 * 10^ 8 N.

We know that the gravitational force has to do with the kind of force that is acting on two or more objects that can be found on the earth. We know that the gravitational force is the force that brings the masses that are on the earth together and this force would always be a kind of an attractive force that is acting on the objects.

We know that from the Universal law of gravitation;

F = G m1m2/r^2

G = Gravitational constant

m1 and m2 = masses of the satellite and the earth respectively

r = distance between the satellite and the earth

Then we have to now substitute the values that we have and then we are going to obtain from solving the problem the following;

F = 6.6 * 10-^ 11 * 987 * 5.97 * 10^ 24/(5.1 * 10^4)^2

Answer:

Alpha decay forms new element with two fewer protons and two fewer neutrons, Beta decay forms new element with one more proton and one fewer neutron. Gamma decay forms NO new element, but now the element has less energy because energy is released as gamma rays.

Explanation:

ANSWER AND EXPLAINATION:
Gamma decay differs from alpha and beta decay in several ways:

1. Particle emitted: In gamma decay, no particles are emitted. Instead, a high-energy photon called a gamma ray is released. Alpha decay involves the emission of an alpha particle, which consists of two protons and two neutrons. Beta decay involves the emission of either a beta-minus particle (an electron) or a beta-plus particle (a positron).

2. Mass and charge: Gamma decay does not change the mass or atomic number of the nucleus since no particles are emitted. Alpha decay reduces the atomic number by 2 and the mass number by 4, as an alpha particle is emitted. Beta decay changes the atomic number, with beta-minus decay increasing it by 1 and beta-plus decay decreasing it by 1. The mass number remains the same in beta decay.

3. Penetrating power: Gamma rays have the highest penetrating power among the three types of decay. They can pass through most materials and require dense shielding (e.g., lead or concrete) to attenuate them. Alpha particles have low penetrating power and can be stopped by a sheet of paper or a few centimeters of air. Beta particles have intermediate penetrating power and can be stopped by a few millimeters of aluminum.

4. Energy release: Gamma decay releases energy in the form of high-energy photons. Alpha decay releases a significant amount of energy since an alpha particle carries substantial kinetic energy. Beta decay releases energy in the form of the kinetic energy of the emitted beta particle.

gamma decay is a process that involves the emission of high-energy photons, while alpha and beta decay involve the emission of particles with mass and charge. Gamma rays have higher penetrating power and do not cause changes in the mass or atomic number of the nucleus, distinguishing them from alpha and beta particles.

Option B; In a mechanical wave, the restoring force is the force that actually causes the oscillation opposite the direction of the displacement from equilibrium.

Oscillation is the repeating or periodic oscillation of a quantity, often in time, around a central value (often an equilibrium point) or between two or more states. A swinging pendulum and alternating current are two common examples of oscillation. Physics can employ oscillations to simulate intricate interactions, as those between atoms.

The beating of the human heart (for circulation), business cycles in economics, predator-prey population cycles in ecology, geothermal geysers in geology, the vibration of the strings in guitars and other string instruments, the periodic firing of nerve cells in the brain, and the periodic swelling of Cepheid variable stars in astronomy are just a few examples of the dynamic systems that exhibit oscillations in nearly every branch of science.

Answer:

Statement of the given problem,

A ball is thrown vertically upwards at 19.6 m/s. For its complete trip (up and back down to the starting position), what is its average speed?

Let H & T denote the maximum height (in m) of the given ball & the time (in s) required for it to reach there.

Hence from above data we get following kinematic relations,

T = [19.6 m/s - 0 m/s)]/(9.8 m/s^2) [9.8 m/s^2 = gravitational acceleration (assumed)]

or T = 2 (s)

H = (19.6 m/s)*(2 s) - (1/2)*(9.8 m/s^2)*(2 s)^2

or H = 19.6 (m)

Therefore,

assuming vertically upward & downward motions are identical with respect to time & distance covered by the given ball,

the required average speed of the ball during its travel up and back down to the starting position

= (total travel-distance)/(total travel-time)

= 2*(19.6 m)/[2*(2 s)]

= 9.8 m/s [Ans]

Answer:

110 m/s

Explanation:

because if you subtract 450 from 340 you get 110

The car's acceleration is 8 m/s².

The car's acceleration can be calculated using the formula:

a = (v_f - v_i) / t

where a is the acceleration, v_f is the final velocity, v_i is the initial velocity, and t is the time taken.

In this case, the car starts from rest (v_i = 0) and reaches a final velocity of 32 m/s in 4 seconds. Substituting these values into the formula, we get:

a = (32 m/s - 0 m/s) / 4 s = 8 m/s²

Therefore, the car's acceleration is 8 m/s².

The rate of change of velocity about time is defined as acceleration. Because it is a vector number, it has both magnitude and direction. Meters per second square is the standard measure of acceleration.

When an it em accelerates, its velocity changes in magnitude, direction, or both. A positive acceleration indicates an increase in velocity, whereas a negative acceleration indicates a decrease in velocity. If an object's velocity is steady, its acceleration is zero.

Answer:

200ml

Explanation:

To determine the final volume of the gas, you can use the ideal gas law, which states that PV = nRT, where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature in kelvins.

If you know the initial pressure and volume of the gas, and you raise the pressure to a new value, you can use the ideal gas law to determine the new volume.

For example, if the initial pressure of the gas is 20.5 kPa, the initial volume is 400 mL, the number of moles of the gas is n, the temperature is T, and the pressure is raised to 80.5 kPa, you can solve for the final volume as follows:

P1V1 = nRT

P2V2 = nRT

V2 = (P1V1)/P2

V2 = (20.5 kPa * 400 mL)/80.5 kPa

V2 = 200 mL

So, the final volume of the gas is 200 mL.

It's important to note that this calculation assumes that the temperature and the number of moles of the gas remain constant. If either of these variables changes, the final volume of the gas will also be different.

The x-position of the third object is 0 and the y-position is √(119L²/144), which is approximately 0.98L.

To find the x-position of the third object at the later time, we can use conservation of momentum. Since the momentum of the system was initially zero, it must still be zero at the later time.

Let's define the direction from left to right as the positive x-direction, and the direction from bottom to top as the positive y-direction.

The momentum of the system in the x-direction is initially zero, and since there are no external forces acting on the system, it must remain zero at the later time. This means that the total momentum of the two objects in the x-direction must be equal and opposite.

From the given information, we know that the x-coordinates of the first and second objects have changed by Δx = L/3 + L/2 = 5L/6. Since the masses of all three objects are equal, the first and second objects must have the same magnitude of momentum in the x-direction, so each must have momentum mΔx/2 to the right.

Therefore, the third object must have momentum mΔx to the left, and since the momentum of the system is zero, the third object must have the same magnitude of momentum in the y-direction as the first and second objects combined.

Using the Pythagorean theorem, we can find the magnitude of the displacement of the first and second objects in the y-direction: √[(L/4)² + (L/3)²] = √(25L²/144)

Therefore, the magnitude of the momentum of the first and second objects combined in the y-direction is 2m√(25L²/144).

Since the third object has the same magnitude of momentum in the y-direction, we can use the Pythagorean theorem again to find its displacement in the y-direction: √(L² - [(5L/12)² + (2L/3)²]) = √(L² - 25L²/144)

Simplifying this expression, we get: √(119L²/144). Therefore, the x-position of the third object is 0 and the y-position is √(119L²/144), which is approximately 0.98L.
