Answer:
All of then are true
I need brainliest so I can rank up
Explanation:
The object move in the direction of the stronger force
This is what e=mc² means.
So rest energy is RH side of equation that is its mass times speed of light squared.
Answer:
The error in tapping is ±0.02828 ft.
Explanation:
Given that,
Distance = 200 ft
Standard deviation = ±0.04 ft
Length = 100 ft
We need to calculate the number of observation
Using formula of number of observation
Put the value into the formula
We need to calculate the error in tapping
Using formula of error
Put the value into the formula
Hence, The error in tapping is ±0.02828 ft.
Answer:
Explanation:
The acceleration of an object is the rate of change of velocity. The mathematical expression for the acceleration of an object is given by :
Where
v and u are final and initial velocities
t is time
or we can write acceleration as :
Hence, this is the required solution.
