Answer:
We conclude that the force on the bag is 500 N.
Explanation:
Given
- Mass m = 1000 kg
- Acceleration a = 0.5 m/s²
To determine
Force F = ?
We know that when a force is applied to a body, it produces acceleration.
<u>Important Tip: </u>
- We can determine the force on the bag using the formula F = ma
Using the formula
where
is the force
is the mass
is the acceleration
now substitute m = 1000, and a = 0.5 m/s² in the formula
N
Therefore, we conclude that the force on the bag is 500 N.
Answer:
The wavelength will be 4 cm, frequency will be 4.66 Hz and wave speed is 18.6 cm/sec
Explanation:
Given:
No. of crest = 13
No. of trough = 15
Time = 3 seconds
Hence, 1 crest or 1 trough =
therefore,
13 C + 15 T =
=
Time given 3 seconds
=
2 cm distance is travelled is time period
Again wave will travel in 1 T = 4 cm
wave speed v =
=
= 18.6 cm/s
