Which statement accurately describes the motion of the object in the graph above over 10 seconds? Group of answer choices The ob
ject is at rest for 3 seconds and then decreases velocity to 1 cm/s for 3 seconds. The object is at rest for 4 seconds and then moves forward for 4 seconds at 1 cm/s. The object moves forward at 1 cm/s, stops, and then increases velocity to 2 cm/s. The object moves forward at 1 cm/s, stops, and then continues at the same velocity.

Determine the torque applied to the shaft of a car that transmits 225 hp and rotates at a rate of 3000 rpm.
Answer:
Torque=0.51 Btu
Explanation:
Given Data
Power=225 hp
Revolutions =3000 rpm
To find
T( torque )=?
Solution
As
As force moves an object through a distance, work is done on the object. Likewise, when a torque rotates an object through an angle, work is done.
So
Answer:
Explanation:
Given:
- volume of oil in the cylinder,
- volume of the oil level when the ice is immersed,
- the volume level of oil when the ice melted,
<u>Now, therefore the volume of ice:</u>
<u>Now the volume of water:</u>
As we know that the relative density is the ratio of density of the substance to the density of water.
<u>So, the relative density of ice:</u>
.....................(1)
as we know that density is given as:
now eq. (1)
where, m = mass of the water or the ice which remains constant in any phase
