Answer:
m1v1=m2v2, v2=4.3m/s KE=(0.5)(2.94)(4.3)=6.2J
Yes
Explanation:
There would be a difference in temperature between the two places over the time interval.
What is temperature?
Temperature is the degree of hotness or coldness of a body. It is measured using a thermometer as described in the set up.
Temperature changes is a result of heat transfer.
The sun is the ultimate source of energy for the earth.
It transfers heat to the earth by radiation.
Under a shade, the tree leaves or shed will cut off the radiation preventing it from reaching the surface. This place will be cool and at a lower temperature than expected.
The thermometer furnished with direct sunlight will have a higher temperature. As the radiation from sun hits the surface, it causes it to warm up and increase in temperature. This will cause the thermometer's temperature to also rise.

Answer:
Magnetic field will be ZERO at the given position
Explanation:
As we know that the magnetic field due to moving charge is given as
so here we know that for the direction of magnetic field we will use
so we have
so magnetic field must be ZERO
So whenever charge is moving along the same direction where the position vector is given then magnetic field will be zero
Answer:
False
Explanation:
If a point charge has electric field lines point into it,then charge must be negative because electric lines point into negative charges and point out of positive charges
