Place the two thermometers outdoors in different locations. Place one in direct sunlight and the other in shade. Make sure that
Archy [21]

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.

A proton moves along the x-axis with vx=1.0×107m/s. As it passes the origin, what are the strength and direction of the magnetic
Sunny_sXe [5.5K]

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

B = \frac{\mu_0 qv sin\theta}{4\pi r^2}

so here we know that for the direction of magnetic field we will use

\hat B = \hat v \times \hat r

so we have

\hat B = \hat i \times (\hat i + 0\hat j + 0\hat k)

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
