Answer:
<h2>The amount of torque put on the car is 33,000Nm</h2>
Explanation:
Formula for calculating torque is expressed as T = rFsin
where;
r is the radius of the of the arm of the jack = 3m
F is the force exerted = 11000
is the angle of rotation = 90°
On substituting;
The answer is Earths rotation
The horizontal force needed to start the calculator moving from rest is 1.5 N
What is Kinetic friction?
It is defined as a force that acts between moving surfaces.
The magnitude of the force will depend on the coefficient of kinetic friction between the two materials.
Here,
weight of calculator, N = 3 N
The coefficients of static frictions, µ (static) = 0.50
The coefficients of kinetic frictions, µ (kinetic) = 0.40
Now,
The horizontal force required = The static friction force
F = µ (static) * weight of calculator
F = 0.50 * 3.0
F = 1.5 N
Hence,
The horizontal force needed to start the calculator moving from rest is 1.5 N

Answer: 1- A diagram showing the forces acting on the object.
2- The force vector describes a specific amount of force and its direction. You need both value and direction to have a vector.
3- A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it.
4- I don’t know
5- When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces
6- By applying an unbalanced force, you can change the motion of an object. Unbalanced forces can make an object at rest start moving, make a moving object stop, or change the direction and speed of the object.
7- If the forces on an object are unbalanced, this is what happens: a stationary object starts to move in the direction of the resultant force.
8- Imbalance or unequal force
9- The result is no motion. Balanced forces can cancel each other out. Any time there is a balanced force, the object does not move.
10- net force is the vector sum of all the forces that act upon an object.
RESTATE THESE

RESTATE!!!!
Answer:
Avion A (10000 meters).
Explanation:
Deje que la altura de los aviones sea A y B respectivamente.
Dados los siguientes datos;
Altura A = 10000 metros
Altura B = 33300 pies
Para encontrar el avión que voló más alto, tendríamos que hacer alguna conversión de unidades.
Conversión:
Metros a centímetros;
1 metro = 100 cm
10000 metros = 100 * 10000 = 1.000.000 centímetros.
Por lo tanto, la altura A en cm = 1,000,000 centímetros
Pies a centímetros;
1 pie = 30,48 centímetros
33300 pies = 33300 * 30,48 = 1014984 centímetros.
Por lo tanto, la altura B en cm = 1014984 centímetros.
De los cálculos anteriores, podemos deducir que el avión A voló más alto.
