time graph reveals pertinent information about an object's velocity. For example, a small slope means a small velocity; a negative slope means a negative velocity; a constant slope (straight line) means a constant velocity; a changing slope (curved line) means a changing velocity.

Answer:

the answer is in the pic below :)

Explanation:

Answer:

\(\boxed {\boxed {\sf v\approx0.24 \ m/s}}\)

Explanation:

Velocity can be found by dividing the displacement by the time.

\(v=\frac{displacement}{time}\)

The displacement is 4.77 meters and the time is 19.5 seconds.

\(displacement=4.77 \ m \\time=19.5 \ s\)

Substitute the values into the formula.

\(v=\frac{4.77 \ m }{19.5 \ s}\)

Divide.

\(v=0.244615385 \ m/s\)

Let's round to the nearest hundredth (just to make the answer more concise).

The 4 in the thousandth place tells us to leave the 4 in the hundredth place.

Tom 75 kg stands in a 25kg canoe that is still in the water. If he jumps east out of the canoe with a speed of 5. 0 m/s,  the recoil speed of the canoe would be 15.0 m/s in the opposite direction (west) when Tom jumps east out of the canoe with a speed of 5.0 m/s. The negative sign indicates the opposite direction of motion.

To determine the recoil speed of the canoe when Tom jumps out, we can apply the principle of conservation of momentum. According to this principle, the total momentum before the jump is equal to the total momentum after the jump.

Initially, both Tom and the canoe are at rest, so the total momentum is zero. After the jump, Tom moves in one direction, and the canoe moves in the opposite direction to conserve momentum.

The momentum of an object is defined as the product of its mass and velocity. The momentum before the jump is given by:

Initial momentum = (mass of Tom + mass of canoe) * 0

The momentum after the jump is given by:

Final momentum = mass of Tom * velocity of Tom + mass of canoe * velocity of canoe

Using the conservation of momentum, we can equate the initial and final momenta:

0 = (mass of Tom + mass of canoe) * 0

0 = mass of Tom * velocity of Tom + mass of canoe * velocity of canoe

Substituting the given values:

0 = 75 kg * 5.0 m/s + 25 kg * velocity of canoe

Solving for the velocity of the canoe:

-75 kg * 5.0 m/s = 25 kg * velocity of canoe

Velocity of canoe = (-75 kg * 5.0 m/s) / 25 kg

Velocity of canoe = -15.0 m/s

Therefore, the recoil speed of the canoe would be 15.0 m/s in the opposite direction (west) when Tom jumps east out of the canoe with a speed of 5.0 m/s. The negative sign indicates the opposite direction of motion.

The force on the 130 cm side is parallel to this combined force, the magnitude of the net force on the loop is 659.0 mN.

To solve this problem, we can use the formula for the magnetic force on a current-carrying wire in a magnetic field: F = I * L * B * sin(theta), where F is the force, I is the current, L is the length of the wire, B is the magnetic field strength, and theta is the angle between the wire and the magnetic field.

a) For the 130 cm side, the angle between the wire and the magnetic field is 0 degrees (since they are parallel), so sin(theta) = 0. Thus, the force on this side is F = I * L * B = 4.00 A * 1.30 m * 75.0 mT = 390.0 mN.

b) For the 50.0 cm side, the angle between the wire and the magnetic field is 90 degrees (since they are perpendicular), so sin(theta) = 1. Thus, the force on this side is F = I * L * B * sin(theta) = 4.00 A * 0.50 m * 75.0 mT * 1 = 150.0 mN.

c) For the 120 cm side, we can use the Pythagorean theorem to find that the angle between the wire and the magnetic field is approximately 36.9 degrees. Thus, sin(theta) = sin(36.9) = 0.6. The force on this side is F = I * L * B * sin(theta) = 4.00 A * 1.20 m * 75.0 mT * 0.6 = 216.0 mN.

d) To find the net force on the loop, we need to add up the forces on each side using vector addition. Since the forces on the 50.0 cm and 120 cm sides are perpendicular to each other, we can use the Pythagorean theorem to find their combined magnitude: sqrt((150.0 mN)^2 + (216.0 mN)^2) = 269.0 mN.

Since the forces on either side of the 130 cm are parallel to one another, we may add them:

269.0 mN + 390.0 mN = 659.0 mN.

The net force acting on the loop is 659.0 mN in size as a result.

If a coronal mass ejection occurs on the Sun that expels material directly toward Earth at a speed of 1,500 kilometers per second (km/s), it would take approximately 17 hours for these charged particles to reach Earth.

Coronal mass ejections (CMEs) are powerful eruptions of plasma and magnetic field from the Sun's corona. The time it takes for a CME to travel from the Sun to Earth depends on the speed of the particles and the distance between the Sun and Earth. Since the distance between the Sun and Earth is about 149.6 million kilometers, and the speed of the particles is 1,500 km/s, it would take approximately 17 hours for the CME to reach Earth. During this time, the particles can interact with the Earth's magnetic field, potentially causing geomagnetic storms and other space weather effects

The statement given here is True and  is  known as the 'Electrostatic Shielding Effect.'

When an electric field is applied to a conductor, the charge is redistributed in such a way that the electric field inside the conductor is canceled out, but there is a net positive charge density on the surface of the conductor.

The reason why the electric field inside the solid conductor points towards the surface of the conductor under electrostatic conditions is due to the fact that there are no charges present in the interior of the conductor.

The electrons in the conductor move towards the surface until the electric field inside the conductor is canceled out. The charges inside the conductor rearrange themselves to reduce the electric field inside the conductor. This process continues until the electric field inside the conductor is zero.

The surface of a conductor that carries a net charge is always perpendicular to the electric field at the surface. As a result, the electric field lines inside the conductor point towards the surface. This phenomenon is known as electrostatic shielding. It helps to protect electrical components inside a conductor from external electric fields by confining the electric field inside the conductor to the surface.

Tension is a contact force that is transmitted via a rope, thread, wire, or other similar material when pressures on the opposing ends are pulling on it. For example, the rope holding a tire swing to a tree limb is strained. The rope is pulled upward by a branch that is fighting the rope's tug tension, which is merely a pulling force, while the rope is pulled downward by gravity. Pushing on a loose rope creates no strain. As a result, the force of tension must always be represented in the direction that the string is pulling the object in a free-body diagram.

The length of the wire is 36 m.

The density is the ratio of the mass and volume of a substance. The density  is given by the formula,

d=m/V

where d is the density. m is the mass and V is the volume.

The density of the material does not change and the initial and final volume of the substance will be equal when it has changed shape provided the mass has not been changed.

The radius r of the sphere is half of its diameter. Therefore, r=6.0/2 = 3.0 cm.

Then volume of the sphere Vs is given by the formula,

Vs=(4/3)*π*r^3

Put the value of r in the above formula.

Vs=(4/3)*3.14*(3.0)^3

Vs=113.04 cm^3

For the cylinder, the radius s=0.2/2 mm = 0.01 cm and the length l is unknown. The volume of the cylinder Vc is given by the formula,

Vc=πs^2l

Put s=0.01 cm in this equation and solve it.

Vc=(3.14)*(0.01)^2l

Vc=0.000314 l cm^2
