Hi there!
Use the equation:
Where m2 and v2 deal with the larger object, and m1 and v1 with the smaller object. Plug in the given values:
v2 = ?
m1 = 0.048 kg (converted)
m2 = 2.95
v1 = 391
If you speed up from the rest to 12m/s in 3 seconds, what is your acceleration?

Answer:
= 391.67 Hz
Explanation:
The sound of lowest frequency which is produced by a vibrating sting is called its fundamental frequency ().
The For a vibrating string, the fundamental frequency () can be determined by:
=
Where v is the speed of waves of the string, and L is the length of the string.
L = 42.0 cm = 0.42 m
v = 329 m/s
=
=
= 391.6667 Hz
The fundamental frequency of the string is 391.67 Hz.
Answer:
The value of resistance when power is 1100 watts = = 50 ohms
Explanation:
Power = 2200 Watts
Resistance = 25 ohms
Power = 1100 Watts
Resistance = we have to calculate
Given that the power in an electric circuit varies inversely with the resistance
⇒ P ∝
⇒ =
⇒ =
⇒ = 50 ohms
This is the value of resistance when power is 1100 watts.
