<span> vernier scale because is a part of vernier calipers.rest of them are parts of other measuring instruments like dial guage, screw guage etc</span>
Explanation:
The object's weight on Earth is 5.0 N, so its mass is:
F = ma
5.0 N = m (10 m/s²)
m = 0.50 kg
The acceleration on the moon is g/6 = (10 m/s²) / 6 = 1.67 m/s².
The velocity it reaches after 3.0 seconds is:
v = at + v₀
v = (1.67 m/s²) (3.0 s) + (0 m/s)
v = 5 m/s
So the momentum is:
p = mv
p = (0.50 kg) (5 m/s)
p = 2.50 kg m/s
Answer:
-140
Explanation:
A gas loses 80joules of heat.
The gas also does 60 joules of work
Therefore the change in internal energy can be calculated as follows
= -80 + (-60)
= -80-60
= -140
Hence the change in internal energy is -140
Answer:
29°
Explanation:
because the refracted ray angle is small than angle of incidence
Answer:
Explanation:
The relationship between angular acceleration α and torque τ is given by :
Here,
is the moment of inertia. It depends on the mass and the distance from the axis of rotation.
is the angular acceleration
Hence, this is the required solution.
