Kinetic energy is the energy of motion. How much kinetic energy does a spherical asteroid with a 1 km diameter have if it is made out of iron (has a density of about 8 kg m-3) and hits Earth at a relative velocity of 10 km s-1?
(i) Does an electron’s electric potential energy increase, decrease, or stay the same as it moves through a circuit? (ii) Does an electron’s kinetic energy increase, decrease, or stay the sams as it moves through a circuit?
4. Kinetic energy is the energy of motion. How much kinetic energy does a spherical asteroid with a 1 km diameter have if it is made out of iron (has density of about 8 kg m-3) and hits Earth at a relative velocity of 10 km s-1? Convert your answer to megatons of TNT (1 megaton of TNT = 4.18 x 1015 joules).
18) What is the total charge on a lizard whose surface area is 4.6 cm2 and who has a surface charge density of 17.6 µC/m2. a. If the lizard was hovering in midair, what electric field strength would be needed to keep the lizard from falling to the ground if it weighed 3g. 19) A ball is held 5m above the ground. What is its potential energy? If it is dropped, how much kinetic energy does the ball have just...
1. How much kinetic energy does an object of mass m traveling with a velocity vx in the x-direction have? 2. How much kinetic energy does an object of mass m traveling with a velocity ~v = vx ˆi + vy ˆj have? 3. Since the pythagorean theorem states that v ^2 = v ^2 x + v ^2 y , we can write the kinetic energy as K = 1/2mv^2 x + 1/2mv^2 y . Does this mean that...
how does activation energy affect kinetic energy? Why is it that you neglect the activation energy of the forward reaction? When oversimplified Eafud is so small that we neglect it Energy Potential energy Reaction coordinate + - + theat
During free fall, how does weight affect kinetic energy, gravitational potential energy, and total energy? (neglecting air resistance) How would this change between a basketball and a beach ball?

How much kinetic energy does a 0.30-kg stone have if it is thrown at 44 m/s? 290
Why does a wire get warm if a current runs through it? A. An electric field in the wire accelerates the charge carriers, increasing their kinetic energy and the thermal energy is nothing but the average kinetic energy of the charge carriers. B.An electric potential difference results in an electric field that accelerates the charge carriers, which frequently collide randomly with stationary atoms, transferring part of their energy to the atoms. C.The charge carriers create an electric field, which accelerates...
