Oksanka [162]3 years ago
3 0

Answer:

Chemical reactions are represented on paper by chemical equations. For example, hydrogen gas (H2) can react (burn) with oxygen gas (O2) to form water (H20). The chemical equation for this reaction is written as: The '+' is read as 'reacts with' and the arrow '' means 'produces'.

The distribution of the fossil fuel depends on the factors like land, temperature, altitude and so on. Because of the difference in all these factors in different areas, there is unequal distribution of fossil fuels.

<u>Explanation:</u>

The problem of allocation of resources arises due to the scarcity of resources, and refers to the question of which wants should be satisfied and which should be left unsatisfied. Because of the scarcity of resources in some areas, there is low production and therefore low growth in that area.

Most natural resources, including fossil fuels, are not distributed evenly around the Earth. Deposits of fossil fuels depend on the climate and organisms that lived in that region millions of years ago, and the geological processes that have since taken place.

Using a diagram explain how acceleration can be obtained from a velocity time graph​
Oksi-84 [34.3K]

Answer:

For any v-t graph the acceleration is the slope of the graph. For average acceleration in a time period ‘t’ consider the change in velocity in time t and divide it by the time t. For instantaneous acceleration you need to go into the realm of differential calculus.

A 50-kg block is at rest on a 15o slope. A force of 250 N is acting on the block up the slope parallel to it. If the block does
Iteru [2.4K]

The minimum value of the coefficient of static friction between the block and the slope is 0.53.

<h3>Minimum coefficient of static friction</h3>

Apply Newton's second law of motion;

F - μFs = 0

μFs = F

where;

  • μ is coefficient of static friction
  • Fs is frictional force
  • F is applied force

μ = F/Fs

μ = F/(mgcosθ)

μ = (250)/(50 x 9.8 x cos15)

μ = 0.53

Thus, the minimum value of the coefficient of static friction between the block and the slope is 0.53.
