Answer:
Equilibrium price will fall and quantity demanded for jelly will also fall
<u>Explanation:</u>
Peanut butter and jelly are consumed together. It means they are complementary goods. These are those goods which are bought together. So increase or decrease in the price of one commodity will automatically affect the demand for another commodity.
When the price of peanut butter increases than people will demand less of peanut butter. Similarly, the demand for jelly is associated directly with the demand for peanut butter. So it will also fall . Due to the fall in the price of jelly and simultaneous fall in demand, the equilibrium price will fall.
Sure !
Start with Newton's second law of motion:
Net Force = (mass) x (acceleration) .
This formula is so useful, and so easy, that you really
should memorize it.
Now, watch:
The mass of the box is 5.25 kilograms, and the box is
accelerating at the rate of 2.5 m/s² .
What's the net force on the box ?
Net Force = (mass) x (acceleration)
= (5.25 kilograms) x (2.5 m/s²)
Net force = 13.125 newtons .
But hold up, hee haw, whoa ! Wait a second !
Bella is pushing with a force of 15.75 newtons, but the box
is accelerating as if the force on it is only 13.125 newtons.
What happened to the rest of Bella's force ? ?
==> Friction is pushing the box in the opposite direction,
and cancelling some of Bella's force.
How much ?
(Bella's 15.75 newtons) minus (13.125 that the box feels)
= 2.625 newtons backwards, applied by friction.
Answer:
The change in momentum of the two cars is equal and opposite
Explanation:
The change in momentum of an object is given by:
where
m is the mass of the object
is the change in velocity
According to Newton Laws of motion, the force experienced by an object is equal to the rate of change of its momentum:
(1)
where
is the time interval during which the force is applied.
According to Newton's third law of motion, the force exerted by vehicle 1 on vehicle 2 during the collision is equal and opposite to the force exerted by vehicle 2 on vehicle 1. Therefore, we can write:
Using (1), we can rewrite this as:
Where are the changes in momentum of car 1 and 2, and is the duration of the collision. Simplifying, we get
So, the change in momentum of the two cars is equal and opposite.
When a motorboat passes by, a disturbance or vibration in the lake water is created which travels in all the directions. A water wave is a combination of longitudinal wave as well as transverse wave. If you are a particle of water in the lake, then you would be hit by nearby water particle which would set you in motion. you would travel up and down forming crest and trough and sideways. The energy would be transported forward, as you would collide with other particle and the wave moves forward. your position would not change. only the energy would be transported.
