Answer: For every force there is a reaction force that is equal in size, but opposite in direction.
Hope it helps:)
Hello
The weight of the object is W=80 N and points downwards, in the vertical direction. The force F exerted by the forearm is perpendicular to the forearm itself, which is at an angle of
above the horizontal; therefore, the angle between the direction of the force F and the direction of the weight P is also
(but upwards). The component of the force F in the vertical direction is
and
must be equal to the weight of the object to compensate it. Therefore we can write
and from this we can find the intensity of the force F:
Water will boil faster at a higher elevation. Air pressure<span> affects the </span>temperature<span> at which </span>water boils quickly but cooking <span>times will take longer at higher </span>altitudes. This is due to a decrease in atmospheric pressure. An example would be putting an egg to boil. Water boils at lower temperature but the egg <span> involves heating a food to a certain temperature, so, cooking would take longer. </span>
That fall between the two extremes, including geese, which produce between ten and twelve offspring each year. What Is Carrying
In the question it is already given that the football player is 80 kg.
Then the mass of the football player = 80 kg
Velocity at which the football player is running = 8 m/s
<span>Kinetic Energy = 0.5 • mass • square of velocity
Now we have to put the known data in this equation to find the actual velocity of the footballer.
</span> <span></span>So
Kinetic Energy of the footballer = 0.5 * 80 * (8 * 8)
= 0.5 * 80 * 64
= 2560
So the Kinetic energy of the footballer is 2560 joules
