Answer:
The metal will have changed temperature more than the water.
Explanation:
As we know that when two objects are mixed at different temperature then due to heat exchange between the two they both reach to same final temperature
This is known as thermal equilibrium
So here we have
Heat given by metal = heat absorbed by water
so we have

since mass of metal is same as that of water
so we have

so here we know that

so temperature change in water must be smaller than that of metal
Answer:
Planet will crash on to the Sun if the tangential velocity becomes zero and Rocket should be fired from Earth's orbit is at 30 m/s and in opposite direction to the Earth orbits the Sun
Explanation:
The orbital velocity of the Earth about the sun is 30 km/s. If we shoot a rocket with 30 km/s with respect to Earth in the opposite direction. Then the two velocity vectors cancel. The resultant velocity would be zero with respect to the Sun. resulting velocity is called as tangential velocity.
Planet will crash on to the Sun if the tangential velocity becomes zero and Rocket should be fired from Earth's orbit is at 30 m/s and in opposite direction to the Earth orbits the Sun
