Physics
1 answer:
kumpel [21]3 years ago
6 0

Answer:

Work done, W = 39.2 J

Explanation:

It is given that,

Mass of the block, m = 2 kg

The block is lifted vertically 2 m by the man i.e the distance covered by the block is, h = 2 m. The man is doing work against the gravity. It is given by :

W=mgh

Where

g is acceleration due to gravity

W=2\ kg\times 9.8\ m/s^2\times 2\ m

W = 39.2 J

So, the work done by the man is 39.2 J. Hence, this is the required solution.

Calculate how much calories you have if you have 8 joule ? please:
goblinko [34]

Answer:

If you have 8 Joules of energy that means you have 1.912 calories.

Explanation:

As we know that one calorie is equal to 4.184 J. We need to calculate in 8 Joules of energy how many calories are present.

We know that,

For 1 calorie = 4.184 J

For ? = 8 Joules

To obtain calories in 8 Joules. Divide 8 by 4.184.

\text { Calorie }=\frac{\text { Joule }}{4.184}

\text { calorie }=\frac{8}{4.184}

calorie=1.912

Therefore, 8 J = 1.912 calorie.
