It takes sunlight 8 minutes to reach earth , so yes
Answer:
The velocity of the seeds relative to the ground as they travel through the air is 2.6 meters per second.
Explanation:
From Physics, we know that the absolute velocity of the seeds () is the sum of the absolute velocity of the farmer () and the velocity of the seeds relative to the farmer (), all measured in meters per second. That is:
(1)
If we know that and , then the velocity of the seeds relative to the ground is:
The velocity of the seeds relative to the ground as they travel through the air is 2.6 meters per second.
Answer:
K.Eₓ = 4 K.E
K.Eₓ = 9 K.E
Explanation:
Th formula for the kinetic energy of a body is given as follows:
---------------equation (1)
where,
K.E = Kinetic Energy of Automobile
m = mass of automobile
v = speed of automobile
For twice speed:
vₓ = 2v
then,
using equation (1):
<u>K.Eₓ = 4 K.E</u>
For thrice speed:
vₓ = 3v
then,
using equation (1):
<u>K.Eₓ = 9 K.E</u>
