A 71 kg man is walking at 2 m/s. Calculate the Kinetic Energy for the man

Physics
1 answer:
Westkost [7]3 years ago
7 0

Answer:

<h2>142 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 71 \times  {2}^{2}  \\  =  \frac{1}{2}  \times 71 \times 4 \\  = 71 \times 2

We have the final answer as

<h3>142 J</h3>

Hope this helps you

The magnitude of the electric current is inversely proportional to the _____ of the circuits in R2D2.
alisha [4.7K]
All you need to know for this question is Ohm’s Law:

V=IR
I=V/R
R=V/I

So, the answer is (3) Resistance, since it is inversely proportional to Current (I=V/R)

What times what equals 400
Radda [10]

If you're willing to consider fractions or decimals,
then there are an infinite number of answers. 
Like (2.5 x 160), and (15 x 26-2/3).

If you want to stick to only whole numbers,
then these 8 combinations do:

1, 400
2, 200
4, 100
5, 80
8, 50
10, 40

How do you know the speed of an electromagnetic wave in a vacuum?
Ivenika [448]
The speed of electromagnetic waves in a vacuum is the same as the speed of light. It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
Hope this helps you (:

Answer:

Equilibrium is reached when demand equals supply.

Explanation:

Demand is the amount that consumers want and can buy of a certain product or service in a specific period of time and at a certain price. On the other hand, the supply is the amount that producers want and can sell of a certain product or service in a specific period of time and at a certain price.

In market equilibrium, the quantity demanded of the product or service equals the quantity supplied, so the price also equals. In other words, when market equilibrium is reached, demand and supply are the same, with their corresponding equilibrium price and quantity.

Two situations can occur:

  • When the quantity demanded is greater than the quantity supplied, the market is in a situation of excess demand.
  • On the other hand, it may happen that the price at which the products are being offered is greater than the equilibrium price and the quantity supplied is greater than the quantity demanded. Then there is an excess supply.

<u><em> Equilibrium is reached when demand equals supply.</em></u>
