Empujamos un baúl 3 metros, para ello aplicamos una fuerza de 200 Newton. ¿Cuál es el trabajo realizado?
Answer:
Trabajo realizado = 600 Nm
Explanation:
Dados los siguientes datos;
Fuerza = 200 Newton
Distancia = 3 metros
Para encontrar el trabajo realizado; Trabajo realizado = fuerza * distancia
Sustituyendo en la ecuación, tenemos; Trabajo realizado = 200 * 3
Trabajo realizado = 600 Nm
14. Saeed is pulling a 6 kg heavy rock with an upward force of 40 N but does not succeed to lift it up. What is the magnitude of the normal force on the rock?
Answer:
58.8 N
Explanation:
The normal force is calculated as equal to the perpendicular component of the gravitational force.
Thus; N = mg
We are given m = 6 kg
Thus;
N = 6 × 9.8
N = 58.8 N
Thus, magnitude of normal force on the rock = 58.8 N

A mass sitting on a horizontal, frictional surface is attached to one end of a spring; the other end is fixed to a wall. 3.0 J of
work is required to compress the spring by 0.20 m. If the mass is released from rest with the spring compressed, it
compresses a maximum acceleration of 15 m/s?.
a) Determine the spring constant.
b) Determine the mass.
d) What is the velocity when the mass reaches maximum acceleration?
c) Deterinine the net force when the mass passes 0.10m compression
d) Determine the acceleration when the mass passes 0.10m compression.
e) Determine the velocity when the mass passes 0.10m compression
Answer:
I started answering this before everything was erases, but briefly
W = 1/2 K x^2 so K = 2 W / x^2 = 6 * 25 = 150
Also F = - K X = 150 * 1/5 = 30 N at max extension
m = F / a = 30 /15 = 2 kg
Since max extension occurs at t = 0 you can write
x = A sin ω t
v = ω A cos ω t
a = -ω^2 A sin ω t note that there is no phase angle here
Also at .1 compression
.1 = .2 sin ω t and sin ω t = 1/2 and ω t = 30 deg = pi / 6
Substiture these values above to get velocity and acceleration when
ω t = 30 deg
Explain why a charged body loses its charge if we touch it with our hand?
if u answer me I can give u brainliest ☺️
Answer:
Explanation: A charged body loses its charge when we touch it with our hand because some of the charge flows through our body to the ground earthing. As a result the charge on the body decreases every time we touch it. This is because of earthing.
Explanation:
yw .
Explanation:
When we touch a charged body, it loses its charge, due to the process of earthing. Our body is a good conductor of electricity. It transfers the charges to the earth

An automobile of mass 1.46 E3 kg rounds a curve of radius 25.0 m with a velocity of 15.0 m/s. The
centripetal force exerted on the automobile while rounding the curve is:
Answer:
Centripetal force = 13140 Newton.
Explanation:
Given the following data;
Mass = 1.46 E3 kg = 1.46*10³ = 1460 kg
Velocity = 15m/s
Radius, r = 25m
To find the centripetal force, we would use the following formula:
Centripetal force = mv²/r
Substituting into the equation, we have;
Centripetal force = (1460*15²)/25
Centripetal force = (1460 * 225)/25
Centripetal force = 328500/25
Centripetal force = 13140 Newton.

Name two devices we use generators in. Describe how they work.
Answer:
There are two fundamental types of generators known as AC (alternating current) and DC (direct current) generators. While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power.
Explanation:
An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. ... Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.
What happens to the arrangement of atoms in matter as it is heated?
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance.

A weightlifter lifts a set of weights a vertical distance of 2.0 m. If a constant net force of 350 N is exerted on the weights, what is the net work done on the weights?
Answer:
700 Joules
Explanation:
The work done equals force times distance. Just multiply your two values there.
Side note: It would be more impressive if he'd done it in 1 second rather than 5. You know why? Because POWER=WORK/TIME. The less time it takes him to lift the weight with the same force and distance, the more powerful he is!

Calculating net force
Answer:
0N.
Explanation:
Net force is the sum total of forces acting on an object.
The Fn which is the net force is
450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)
= 450-250+(-600)+ 600+0+250-450
= 0N
The net force is 0

A wagon of mass 42 kg is pushed by a student a distance of 12.2 meters, and 297 j of work was done on the wagon force did the student apply is 24.34 N.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
work = force*distance
force = work/distance
force = 297/12.2
force = 24.34 N

A 96 kg man is standing in an elevator. The man experiences a net force when the elevator moves at an acceleration of 4.0 m/s2 upward and downward. Find both net forces
Answer:
The net upward force the man experiences is approximately 1,324.8 N
The net downward force the man experienced is approximately 556.8 N
Explanation:
The given mass of the man, m = 96 kg
The acceleration of the elevator, a = 4.0 m/s²
According to Newton's third law of motion which states that action ad reaction are equal and opposite, when the elevator moves upwards, we have;
The net force the man experiences, F = Gravitational force, m·g + The force of the elevator pushing upwards, m·a
∴ ↑F = m·g + m·a
Where;
F = The net force the man experiences
m = The mass of the man = 96 kg
g = The acceleration due to gravity ≈ 9.8 m/s²
a = The acceleration of the elevator = 4 m/s²
∴ ↑F = 96 kg × 9.8 m/s² + 96 kg × 4 m/s² ≈ 1,324.8 N
The net upward force the man experiences ≈ 1,324.8 N
When the elevator moves downwards, we have;
The net force the man experiences, F = Gravitational force, m·g + The loss of the gravitational force as the floor moves further downwards, -(m·a)
∴ F = m·g + -(m·a) = m·g - m·a
F = m·g - m·a
∴ ↓F = 96 kg × 9.8 m/s² - 96 k × 4 m/s² ≈ 556.8 N
The net downward force the man experienced ≈ 556.8 N
