Answer:


Explanation:
(a)
Given:
- mass of comet,

- velocity of the comet,

<u>Now, the kinetic energy of the comet can be given by:</u>



(b)
Given:
- energy released by 1 megaton of TNT,

<u>Now the kinetic energy of the comet in terms of energy of 1 megaton TNT:</u>

i.e.

For the answer to the question above,
<span>There is nothing in the equations to suggest that the string moves in the x direction so D) v_x(x,t)=0.

y(x,t) = A sin(kx-omega t)
d{y(x,t)}/d{x} = A k cos(kx - omega t)
Answer:
The distance of fly travel is 115.06 m.
Explanation:
Given that,
Distance = 115 mm
Speed = 1.10 m/s
Speed of fly = 2.20 m/s
We need to calculate the relative speed
Using formula of relative speed

Put the value into the formula


We need to calculate the time for the two steamrollers to meet each other
Using formula of time

Put the value into the formula


We need to calculate the distance of fly travel
Using formula of distance

Put the value into the formula


Hence, The distance of fly travel is 115.06 m.
The sun <u><em>appears</em></u> brighter than any other star.
(It isn't really, but it looks that way because it's much much much much much much closer to us than any other star.)
Answer:
Yes
Explanation:
The farther something is from the center of mass of an object such as a planet, the lower the gravitational force between them
F = GMm/d²
