Answer:
1144.8
Explanation:
1 meter per second is equal to 3.6 kilometers per hour
Answer:
-14.2m/s
Explanation:
Given parameters:
Initial velocity of the ball = 25m/s
Time = 4s
Unknown:
Final velocity of the ball = ?
Solution:
To solve this problem, we use the expression below;
v = u - gt
v is the final velocity
u is the initial velocity
g is the acceleration due to gravity
t is the time
v = 25 - (9.8 x 4) = -14.2m/s
I really think it could be a 23 kg
The electromagnetic spectrum spans a variety of radiation types including x-rays all the way through to radio waves. Humans are able to only see in the visible part of the electromagnetic spectrum (390-700nm) but bees can see ultraviolet radiation (10-100nm). Lower wavelength electromagnetic waves have more energy. Hence, compared with humans, bees can sense electromagnetic waves that have more energy.
