That's tin
d = m/v
42.5/ 5.8
which comes around 7.3 g/ml and matches with the density of the tin metal
answers
velocity = 7 m/s
tension = 7.644 N
set up equation for velocity
because energy is conserved, the change in potential energy as the potato drops is the same as the change in kinetic energy
U = K
mgh = m/2
gh = /2
= 2gh
v =
values
g = 9.8 m/s^2
h = 2.5 m (change in vertical distance)
plug in values and solve
v =
v =
v = 7 m/s
set up equation for tension
at the lowest point, tension (directly upward) acts in the opposite direction of weight (directly downwards) so
∑F = T - mg
since the potato is in circular motion, the net force is equal to centripetal force
∑F = m/r
∑F = T - mg = m/r
T - mg = m/r
T = mg + m/r
T =
values
m = 0.26 kg
g = 9.8 m/s^2
v = 7 m/s
r = 2.5m
plug in values and solve
T =
T =
T = 7.644 N
The answer to this question is "Greater than". As per the OSHA or Organizational Health and Health Organization, a noise level of 95 DB or decibels is greater than the lowest level at which hearing protection is required in 85 decibels and the person's exposure should be limited only to six hours or less than of it.
Answer:
Motor converts Electrical energy into Mechanical Energy, while A generator converts Mechanical energy into Electrical energy. thankyou
Explanation:
Answer:
Gravity force
Explanation:
We are given that
Mass of wooden block,m=1.85 kg
We have to find the force which do non zero work on the block as it slides down the ramp.
When a block slides down the ramp on a frictionless surface .
Then, weight act on the wooden block in downward direction.
We know that weight is that force which act on the body due to gravity.
Then, we can say that the force which do nonzero work on the block as it slides down the ramp is gravity force.
