Answer:

Work done = 1320000J or 1.32 × 10^6J

Explanation:

power =22kw = 22000w

Time = 60seconds

From: power = work done/ Time

work done = power × time

work done = 22000 × 60

work done = 1320000J or 1.32 ×10^6 J

Answer:

13.2 x 10^5 J

Explanation:

Power = work/time

Given

Power = 22kw

= 22 x 1000 = 22000w

Time = 60 secs

Therefore

22000 = work/60

Cross multiply

Work = 22000 x 60

= 1320000

= 13.2 x 10^5J

Q7:<br> A 4 kg toy is lifted off the ground and falls at 3 m/s. What is the toy's energy?
alexandr1967 [171]

Answer:

The toy's energy is 18 J.

Explanation:

We have, a 4 kg toy is lifted off the ground and falls at 3 m/s. It is required to find toy's energy.

The toy will have kinetic energy due to its motion. The energy is given by :

E=\dfrac{1}{2}mv^2\\\\E=\dfrac{1}{2}\times 4\times 3^2\\\\E=18\ J

So, the toy's energy is 18 J.

_____________ part of this layer has a relatively homogeneous composition, while the other part is less uniform in composition
Over [174]

Answer:

Oceanic part of this layer has a relatively homogeneous composition, while the other part is less uniform in composition

Explanation:

Your question is base on the earth crust which is either oceanic crust or continental.

The earth Lithosperic layer is divided into two part namely the oceanic crust and the continental crust.

The oceanic crust is more uniform in composition than the continental crust because of the kind  of earth events that is predominant here. For example sea floor spreading  . The oceanic crust is composed dominantly of Mafic rocks. The Mafic rocks are extrusive igneous rocks. This rocks are formed when magma intrudes into the ocean surface, due to rapid cooling this rocks solidified quickly to form these rocks that are mainly basaltic. The oceanic rocks are dominantly basaltic. The basaltic dominance makes the oceanic crust relatively homogeneous in composition.

Events like sea floor spreading whereby the oceanic floor diverge forming two parts are one factors that causes mantle materials(molten magma) to reach the surface to form this basaltic rocks. The separating  point, the mid oceanic ridges is where new crust are formed from the up-welling of magma.  As you move away from the mid oceanic ridges the rocks become older.
