Answer:

In a camping fire conduction serves to transfer heat through the ground from where the fire is located, spreading out in a gradual, spherical pattern. This often goes unnoticed by people who sit close to a fire, but as the ground warms, convection currents moving across it also transfer some of this heat from the solid surface to the air as well.

To start the control would be import to see how drivers would act with full focus on the road. The subjects should (in order for the only difference to be the phone) is to use the same vehicle same road same weather condition, just obviously one has the phone the other does not. I hope this helps

The mass of block B is twice the mass of block A, while the mass of the pulley is equal to the mass of block A. The blocks are l

Answer:

C)the right cord pulls on the pulley with greater force than the left cord

Explanation:

As we can see the figure that B is connected to the right string while A is connected to the left string

Now force equation for B as it will move downwards is given as

$(2m)g - T_B = (2m)a$

similarly for block A which will move upwards we can write the equation as

$T_A - mg = ma$

now we know that pulley is also rotating so the tangential acceleration of the rope at the contact point with pulley must be same as that of acceleration of the blocks

so here pulley will rotate clockwise direction

So tension in the right string must be more than the left string

So correct answer will be

C)the right cord pulls on the pulley with greater force than the left cord
