Answer:
To change.
Explanation:
The Law of Conservation of energy states that energy cannot be destroyed but can only be transformed or converted from one form to another. For example, light energy to heat energy.
When a material absorbs energy from light the energy causes the material to change.
D because it includes both acceleration and direction.
We Know, F = m*a
Here, F = 10 N
m = 1 Kg
Substitute their values in the equation,
10 = 1 * a
a = 10/1
a = 10
So, your final answer & the acceleration of the object would be 10 m/s²
Hope this helps!
Answer:
1.46× 10^-8 N
Explanation:
F=Gm₁m₂/r²
F=(6.67×10⁻¹¹ × 50× 70)/(4)²
F=1.46× 10^-8 N
Hope, this helps you.
Answer:
Δt = 0.315s
Explanation:
To calculate the time difference, in which both fans hear the batterstrike, you first calculate the time which takes the sound to travel the distances to both fans:


d1: distance to the first fan = 18.3 m
d2: distance to the second fan = 127 m
vs: speed of sound = 345 m/s
You replace the values of the parameters to calculate t1 and t2:

The difference in time will be:

Hence, the time difference between hearing the sound at the location s of both fans is 0.315s
