An airplane traveling 1000 m above the ocean at 140 km/h is going to drop a box of supplies to shipwrecked victims below.(b) What is the horizontal distance between the plane and the victims when the box is dropped?

Answers

Answer 1

Answer:

Answer:

Horizontal distance = 555.74 m

Explanation:

Given the following data;

Height = 1000m

Horizontal velocity = 140km/h

First of all, we would convert the unit of the velocity to meters per seconds;

V = (140 * 1000)/60*60

V = 140000/3600 = 38.89m/s

To find the time, we would use the second equation of motion;

$S = ut + \frac {1}{2}at^(2)$

We know that acceleration due to gravity, g is equal to 9.8m/s²

Initial velocity, u = 0

Substituting into the equation, we have;

$1000 = 0(t) + \frac {1}{2}*9.8*t^(2)$

$1000 = 0 + 4.9*t^(2)$

$1000 = 4.9*t^(2)$

$t^(2) = \frac {1000}{4.9}$

$t = √(204.08)$

Time, t = 14.29 secs

To find the horizontal distance;

Speed = distance/time

$Horizontal \; distance = horizontal \; velocity * time$

$Horizontal \; distance = 38.89 * 14.29$

Horizontal distance = 555.74 m

What does it mean to be a socially responsible consumer? Use an example to support yourexplanation.

Answers

A socially responsible consumer is a consumer who cares about the social impact that the products he buys have on the world around him. Socially responsible consumers avoid products that they think harm society. Instead, they buy goods and services from companies that they believe do a better job of taking care of the world.

An example of such a behaviour would be a person who shops in small stores as opposed to shopping in supermarkets, because he believes that it is important to support local businesses. Another example is that of someone who buys free trade coffee, in order to ensure that his purchase does not have a negative impact on coffee farmers around the world.

Answers

The primary function of dietary vitamins is to activate enzymes. The correct option is D.

What are dietary vitamins?

Dietary supplements are substances that you may use to supplement your diet with nutrients or to reduce your risk of healthproblems such as osteoporosis or arthritis.

Dietary supplements are available in pill, capsule, powder, gel capsules and tablets, extracts, or liquid form.

Vitamins and minerals are regarded as essentialnutrients because, when combined, they perform hundreds of functions in the body.

They strengthen bones, heal wounds, and boost your immunesystem. In addition, they convert food into energy and repair cellular damage.

These chemical reactions are initiated or accelerated by enzymes derived from specificvitamins. For example, B vitamins aid in the formation of active enzymes, which aid in the transfer of energy from the food we eat to the body.

Thus, the correct option is D.
