Answer:
the filling stops when the pressure of the pump equals the pressure of the interior air plus the pressure of the walls.
Explanation:
This exercise asks to describe the inflation situation of a spherical fultball.
Initially the balloon is deflated, therefore the internal pressure is equal to the pressure of the air outside, atmospheric pressure, when it begins to inflate the balloon with a pump this creates a pressure in the inlet valve and as it is greater than the pressure inside, the air enters it, this is repeated in each filling cycle, manual pump.
When the ball is full we have two forces, the one created by the external walls and the one aired by the pressure of the pump, these forces are directed towards the inside, but the air molecules exert a pressure towards the outside, which translates into a force. When these two forces are equal, the pump is no longer able to continue introducing air into the balloon.
Consequently the filling stops when the pressure of the pump equals the pressure of the interior air plus the pressure of the walls.

Calculate the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.
Answer: The rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
Explanation:
The rate of energy transfer from one point to another is known as power.Its SI. unit is Watt.Formula to compute power:
Power = [tex]I^2 R[/tex], I = cureent, R = resistance.
Given R = 5 ohm , Current = 0.5 A.
Then, power = [tex](0.5)^2\times 5=0.25\times5=1.25\ watt[/tex]
Hence, the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
POSS An apple with a mass of 2 kg falls from a tree with an acceleration of 9 "What is the net force of the apple as it hits the ground?
Answer:
F = 19.62[N]
Explanation:
By means of Newton's second law which tells us that the sum of the forces on a body is equal to the product of mass by acceleration, we can determine the force.
[tex]F=m*a[/tex]
where:
F = force [N]
m = mass = 2 [kg]
a = gravity acceleration = 9.81 [m/s²]
Now replacing:
[tex]F=2*9.81\\F=19.62[N][/tex]
Which wave, A or B, has higher energy?
A
O A, because it has a higher amplitude
OB, because it has a higher amplitude
O A, because it has a lower amplitude
OB, because it has a lower amplitude
АЛЛА
B
Answer:
Wave A.
Explanation:
The energy of a wave is directly proportional to the square of the amplitude.
If a wave has higher amplitude, it will have more energy. On the other hand, a wave having lower amplitude, it will have less eenergy.
In this case, we need to tell which wave has higher energy. Hence, the correct option is A because it has a higher amplitude.

A box of mass m is held at rest on a frictionless surface with force F up the ramp. The ramp has an angle
What is the magnitude of the normal force?
Choose 1 answer:
The magnitude of the normal force is to be considered as the mg cos θ when the box of mass m is at rest.
What is magnitude?In terms of physics, it refer to the maximum size where it should be extended also it defined the object direction. It is factor for vector and the scalar quantities.
When the box of mass m should be at rest so here the ramp should be an angle so here the weight should be perpendicular to the string.
hence, The magnitude of the normal force is to be considered as the mg cos θ when the box of mass m is at rest.

A box weighing 12 Newtons is dragged across a
rough floor with a constant velocity of 1.4 meters
per second. The horizontal applied force pulling
the box is 8.5 Newtons. What is the magnitude of
the friction force the floor exerts on the box?
Your answer
PLEASE ANSWER
Answer:
The magnitude of the friction force that the floor exerts on the box is 8.5 newtons.
Explanation:
From Newton's Laws of Motion and given that box is moving at constant velocity, the net acceleration of the box is zero, meaning that magnitude of friction force is equal to the magnitude of the horizontal applied force. Please notice that friction force is the reaction to the horizontal force. The equation of equilibrium for the box is:
[tex]\Sigma F = F - f = 0[/tex] (1)
Where:
[tex]F[/tex] - Horizontal applied force, measured in newtons.
[tex]f[/tex] - Friction force, measured in newtons.
If we know that [tex]F = 8.5\,N[/tex], then the magnitud of the friction force that the floor exerts on the box is:
[tex]f = F[/tex]
[tex]f = 8.5\,N[/tex]
The magnitude of the friction force that the floor exerts on the box is 8.5 newtons.

when operating a heater of 1500 watts for 3 hours per day the consumed energy and the total cost of 25 dirhams during a month (30 days) are ... and ...?
Answer:
I. Consumed energy = 4.5Kwh
II. Total cost = 3375 Dirhams
Explanation:
Given the following data;
Power = 1500W
Time = 3 hours
To find the energy consumption;
Energy = power * time
Substituting into the equation, we have;
Energy consumption = 1500 * 3
Energy consumption = 4500 watt-hour = 4.5Kwh (1 Kilowatts is equal to 1000 watts)
To find the total cost;
Daily cost = Energy consumption * cost
Daily cost = 4.5 * 25
Daily cost = 112.5 Dirham
Therefore, monthly cost = 112.5 * 30
Monthly cost = 3375 Dirham.

3.Most asteroids are made of different kinds of rocks, but some have clays or metals, such as nickel and iron.
Explanation:
it is simple really u just need to remember that astorids do not orbit a sun they crash into things like planets and mess them up really bad if they hit our sun which might happen it will just burn up because our sun is so hot that it can burn stuff if a astorid hits earth it wont be to bad for our earth at all it might cause some damage but we will be fine.

A 1,200 kg car travels at 20 m/s. what is its momentum?
Answer:
The answer is 24 000kgm/s.
Explanation:
Given that the formula for momentum is p = m×v where m represent mass and v is speed :
let m = 1200, v = 20
p = m × v
p = 1200 × 20
p = 24 000 kgm/s

a car is moving at 4m/s has 500N force driving it forward and air resistance of 500N. Describe the motion of the car
Answer:
See the explanation below.
Explanation:
We know from Newton's second law that the sum of forces on a body is equal to the product of mass by acceleration. In this way, we have the following equation.
∑F = m*a
where:
∑F = sum of the forces [N] (units of Newtons)
m = mass of the car [kg]
a = acceleration [m/s²]
Therefore we have two forces one that drives the car forward and another that opposes the movement.
[tex]500-500 = m*a\\m*a=0\\a=0[/tex]
This tells us that the acceleration is zero and therefore the movement is with constant speed. That is, the speed does not vary during the movement of the vehicle.
