Answer:
B.Focused,warm
Explanation:
when the rays are focused more energy an area recieves and it is warmer there.
Answer:
Explanation:
according to resultant of two parallel forces,
Fpivot = Fobject + Fbricks
so that, the net force is zero
Air resistance is a type of friction.
Answer:
The angle of the launch is 17.09 degrees.
Explanation:
Given that,
The initial speed of a cannon is 100 m/s
It is launched at some angle and it lands after being in the air for 6 s.
We need to find the angle of the launch.
The time taken by the projectile to reach the ground is called the time of flight. It is given by the formula as follows :
Here, = launch angle
Hence, the angle of the launch is 17.09 degrees.
It causes space to expand.
Gravity and Dark energy have been in a interstellar tug of war since the universe's inception. Gravity tries to pull things together, while Dark energy pushes things apart. It may remain this easy until one of these forces dominate.
