Answer:
A ramp
Explanation:
An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists.
Explanation:
They will have not much control over their speed or rotational energy. they will carry a lot of gravitation potential energy which will get converted to kinetic energy as they fall through the atmosphere. They will reach their terminal velocity, the fastest they can travel with earth's gravity before they pull their parachute, when they use a parachute to extend their surface area, increasing wind resistance. this allows them to land safely.
The correct answer to the question is : A) Tossing it horizontally at a faster speed.
EXPLANATION:
Before going to answer this question, first we have to know the horizontal distance covered by any body when it is fired parallel to the ground.
Let us consider a body of mass m is fired with velocity u parallel to the ground. Let it was projected at a height h from the ground.
Hence, the horizontal distance covered by the projectile is calculated as -
Horizontal distance R = 
.
Here, g is known as the acceleration due to gravity.
From above, we see that more is the initial velocity, the more is the horizontal distance covered by it i.e the more is the widest curved path.
Hence, the correct answer to the question is that tossing a ball horizontally at a faster speed will trace out the widest curved path.
Vector resolution will be used to answer this question as the boat's velocity will have two components, one allowing it to travel across the river and the other taking it downstream.
According to Boyle's Law, volume is inversely proportional to pressure. It means
if the volume of a gas goes up the pressure goes down and if the volume of the gas goes up the pressure goes down. When the pressure of air inside the inflated balloon is more than the atmospheric pressure outside the balloon. And also when the density inside is greater than the density outside. The molecules inside the balloon move and bang around the inner walls which produces force, which provides the pressure of an enclosed air.
