Answer:
F = 263.51 N
Explanation:
given,
diameter of wheel = 78 cm
diameter of axle = 14.8 cm
Force exerted on the rim of wheel = 150 N
Force applied outside the axle = ?
To prevent rotation wheel from rotating the Force 'F' should be applied outside of the axle.
Net momentum about the center of mass should be zero
now,
Moment of about center due to 150 N = moment about center due to F on axle
7.4 F = 1950
F = 263.51 N
Hence, Force exerted outside of the axle in order to prevent the wheel from rotating is equal to 263.51 N.
Answer:
400X
Explanation:
Total magnification = power of eyepiece (ocular) × power of the objective lenses
= 10X × 40X = 400X
Acceleration = velocity / time.
B IS YOUR ANSWER.
Soft sound has small amplitude and louder sound has large amplitude. Since, the second wave has large amplitude, it will have the loudest sound.
Answer:
Acceleration:
Final velocity:
Explanation:
To calculate the acceleration, you start from the formula:
Thus:
Now that you have the accelration, you can use the this formula to calculate the final speed:
Thus:
