Answer:
O ice
Explanation:
Albedo refers to the proportion of the incident light that is reflected by a surface to the amount of incoming light.
Here, only <u>ice</u> will reflect even some amount of light. Pavement and dirt do not reflect at all, meanwhile, where glass reflects slightly.
Answer:
40m/s
Explanation:
The horizontal component of velocity remains constant because there are no external forces in that direction
By applying motion equations, V= U+ at
where ,
- v - final velocity
- u - initial velocity
- a-acceleration
- t - time
v = u +at
As no force act on the ball ( we neglect air resistance here) no acceleration is seen,
So v = u = 40m/s
What we must know to determine the direction of the magnetic force on a charge are;
- The direction of the magnetic field.
- The velocity of the charge.
<h3>How to find the direction of magnetic force?</h3>
The magnetic force is the force of attraction or repulsion that emerges between electrically charged particles since of their movement.
From right hand rule, to determine the direction of the magnetic force on a charge, we must know;
- The direction of the magnetic field.
- The velocity of the charge.

<span>Without convection, the equator would stay smoldering hot, the poles would stay well in the deep freeze, and places in between would be in between. The currents move the warm air and warm water from the tropics up to the poles and move cold air and water from the poles down to the tropics. Until now, the coasts have enjoyed milder weather because of the convection currents. -Hope this helps!</span>
