Calculate the kinetic energy of a .30 kg ball thrown at a velocity of 96.6 m/hr in J.

Physics
1 answer:
spin [16.1K]3 years ago
4 0

Answer:

1.08 x 10^-4 J

Explanation:

mass of ball, m = 0.3 kg

Velocity of ball, v = 96.6 m/hr

First convert m/hr into m/s.

As we know that 1 hour = 3600 second

So, 96.6 m / hr = 96.6 / 3600 m/s = 0.0268 m/s

The formula for the kinetic energy is given by

Kinetic energy = 1/2 mv^2

Kinetic energy = 0.5 x 0.3 x 0.0268 x 0.0268 = 1.08 x 10^-4 J

How can submarines use echolocation to tell how close they are to the bottom of the ocean?
Lapatulllka [165]
To locate a specific target or to determine how close submarines are to the seafloor, they use active and passive sound navigation and ranging (or a SONAR, in simple terms.) It emits pulses of sound waves that travel through the water, reflect off the target and relayed back to the ship. By determining how fast the sound wave travels back, the computers on the sub calculate how far they are from the target.

Hope this helps.

Name three bright Saturn ring features, and explain why they are so bright.
Leviafan [203]

The F Ring, the Cassini Division, and the C Ring are bright ring features. They are bright due to the low concentration of materials within them, which allows sunlight to shine through.

The speed at which the objects were attracted to each other determined by the gravitational pull.

<h3>What is gravity?</h3>

The force of attraction felt by a person at the center of a planet or Earth is called as the gravity or gravitational pull.

The gravitational force, Fg is the attractive force exerted by the Earth on the object that is equal to the mass of the object times the gravitational acceleration.

When the two objects are attracted, the speed with which they are moving toward each other depends on the strength of the pull force. This pull force is the gravitational pull.

Thus, the speed at which the objects were attracted to each other determined by the gravitational pull.
