Answer:
7.5 J
Explanation:
To answer the question given above, we need to determine the energy that will bring about the speed of 1 m/s. This can be obtained as follow:
Mass (m) = 15 Kg
Velocity (v) = 1 m/s
Energy (E) =?
E = ½mv²
E = ½ × 15 × 1²
E = ½ × 15 × 1
E = ½ × 15
E = 7.5 J
Therefore, to change the speed to 1 m/s, the employee must do a work of 7.5 J.
Answer:
Dark matter does not affect our view, humans can see through them.
Explanation:
They do not affect our view because we can see right through the (weakly interacting) dark matter, as they do not interact or interfere with electromagnetic force.
Dark matter are often invisible substances and are difficult to spot because they don't absorb or reflect light.

Answer:
Explanation:
Given:
- mass of ice block,
- initial temperature of ice block,
- initial temperature of water,
- final temperature of mixture,
- specific heat of ice,
- specific heat of water,
- Latent heat of fusion of water,
<em>Now, assuming that there is no heat loss out of the mixture:</em>
⇒ heat absorbed by the ice = heat rejected by the water
