Calculate the power of a crane if it lifts a load of 2400N through a height of 10m in 15 seconds.Also express the power in horse
dem82 [27]

Answer:

<h2>2.08 hp</h2>

Explanation:

The power of the crane can be found by using the formula

p =  \frac{f \times d}{t}  \\

f is the Force

d is the distance

t is the time taken

From the question we have

p =  \frac{2400 \times 10}{15}  =  \frac{24000}{15}  \\

We have

power = 1600 W

But 1 W = 0.0013 hp

So 1600 = 2.08 hp

We have the final answer as

<h3>2.08 hp</h3>

Hope this helps you

Explanation:

One common property with all halogens in group 7 is that they are all non-metals.

Fluorine, chlorine, Bromine and Iodine are classified as non-metallic elements and they have a high electronegativity.

  • In chemical reactions, they are very reactive because they require just one electron to complete their octet configuration and be isoelectronic with noble gases.

The most prominent observation from halogens is that they all non-metallic in nature.

What happens when there is a change in pressure at any point in a fluid
Hunter-Best [27]
A change in pressure applied to an enclosed fluid is transmitted undiminished to every point of the fluid and to the walls of the container. This is a statement of Pascal's Principle, which is the basis of the hydraulic jack you see lift cars at the garage.
