mass of the cart?
a. 80N
b. 80 kg
C. 20 N
d. 20 kg
The mass of cart pushed by a 40 Newton force moving with an acceleration of 0.5 m/s² is 80 Kg.
In order to move a body ofmass 'm'kg with an acceleration of 'a' m/s², a force of magnitude → |F| = ma is needed to push the body in a specified direction.
Given is a cart pushed by a 40 Newton force moving with an acceleration of 0.5 m/s².
Mass of block = m Kg [assume]
Force on cart [F] = 40 N
Acceleration of cart [a] =0.5 m/s²
From the definition of force -
|F| = ma
m = |F|/a
m = 40 / 0.5
m = 80 kg
Therefore, the mass of cart pushed by a 40 Newton force moving with an acceleration of 0.5 m/s² is 80 Kg.

Answer: 3
Explanation:
Answer:
So it will lift the mass by h = 17 m
Explanation:
As per energy conservation we know that
here we know that
now we have
so work done by the engine is 250 J
now we have
The birds can glide in the air without moving their wings by maintaining the thrust of the air by their weight and move downward at a very slower rate.
Further Explanation:
The birds have a capability of flying high in the air without flapping their wings and still not falling down rather they glide downwards due to the up thrust of the air. This technique of the birds to keep them in the air without flapping their wings is termed as soaring.
The soaring birds make use of the air current and its thrust on their primary wings so that there is no turbulence experienced by them due to the pointed tips of their primary wings.
The birds should possess some mass in order to maintain a balance between the thrust and the weight of their body. That’s why the small birds are not able to maintain their flight but the bigger birds like vulture, eagle etc. experience sufficient air drag in order tio maintain their flight.
Thus, the birds can glide in the air without moving their wings by maintaining the thrust of the air by their weight and move downward at a very slower rate.

out onto the rear seats. Why does this happen?
Answer:
See the explanation below
Explanation:
This happens because the coffee was at rest, at the time when the car accelerates to move forward the container containing the coffee also accelerates in the same direction, the liquid when moving suddenly spills. The same will happen if the car slows down, any sudden movement changes will cause the coffee to spill, understood by sudden movements when it accelerates or slows down.
Answer:
This happens because of inertia.
Explanation:
Inertia is the ability of a body to remain in its state of rest or relative movement, while an external force is not acting on it.
It is when a body objects to modifying its state of relative rest or movement, including the speed and direction in which this happens.
When a car accelerates, a cup of coffee sitting in a cup-holder spills out onto the rear seats, because it has left its state of rest due to the acceleration force of the car.
The positive and negative electrons split in the cloud
Positive going to the bottom of the cloud and negative to the top.
Since you are made of negative electrons, you attract the positive electrons to you causing you to get struck by lightning.
The ground has negative electrons too!
This will shock the ground and end up shocking you as well, since the ground and you are connected.
Lightning and thunder are connected! They do happen at the same time. The reason why the thunder travels later than the lightning is because you are away from the lightning and the sound waves are just getting near you
B.) How are thunderstorms dangerous?
Thunderstorms are dangerous because they give off positive energy. If you are standing outside while a thunderstorm is in session, you could get shocked since you are made of negative energy and attract positive energy.
If your hair is sticking straight up, you are about to be struck by lightning. Crouch down and cover your head next to your ears and prepare for impact.
You might ask, "Why can't I just run from the lightning?" That is true, but since you aren't faster than light itself, you will still wind up caught in the storm.
Avoid this by staying inside.
Hope this helps <3
