If
you lift a 5 Kg bowling ball with a force of 49 N to a height of 40 m, what is the amount of work done on the
bowling ball to lift it?
Answer:
Workdone = 1960 Joules.
Explanation:
Given the following data;
Mass = 5kg
Force = 49N
Height (distance) = 40m
To find the workdone;
Workdone = force * distance
Substituting into the equation, we have;
Workdone = 49*40
Workdone = 1960 Joules.
Therefore, the amount of work done on the bowling ball to lift it is 1960 Joules.
Para el siguiente conjunto de medidas, calcule EL ERROR RELATIVO PORCENTUAL: 1.34 m, 1.35 m, 1.37 m y 1.36 m
Answer:
Ver explicacion abajo
Explanation:
En este caso para poder calcular el error relativo porcentual, es necesario calcular primero el error absoluto, que se calcula de la siguiente forma:
Error absoluto = Resultado exacto - aproximación
Sin embargo, no tenemos el resultado exacto de las medidas, pero podriamos conocerlo tomando el promedio de estas medidas y este es el que tomaremos como el verdadero resultado de las medidas:
Promedio de medidas = 1.34 + 1.35 + 1.37 + 1.36 / 4
Promedio de medidas = 1.355 m
Ya que tenemos el promedio, podemos calcular el error absoluto de cada medida y luego el error relativo porcentual:
Ea1 = 1.355 - 1.34 = 0.015
Ea2 = 1.355 - 1.35 = 0.005
Ea3 = 1.37 - 1.355 = 0.015
Ea4 = 1.36 - 1.355 = 0.005
Ya que tenemos los 4 errores absolutos, es posible calcular el porcentual:
%error relativo = (Error absoluto / resultado exacto) * 100
Aplicando la expresión con cada uno de los valores tenemos:
%Er1 = (0.015/1.34) * 100 = 1.12%
%Er2 = (0.005/1.35) * 100 = 0.37%
%Er3 = (0.015/1.37) * 100 = 1.09%
%Er4 = (0.005/1.36) * 100 = 0.37%
Espero que te sirva.

Explanation:
back ground radiation is a natural radiation so basically everything emits background radiation. so if it were harmful, the world wouldn't be here,
so it is false
it knocks electrons out of atoms, this is because ionising radiation is a radiation that had enough energy to remove electrons form the atoms and molecules.
true because exposure to radon can damage biological molecules such as proteins, which leads to abnormal patterns of cell division, which leads to cancer.

Answer:
5 kg
Explanation:
Acceleration = 6 m/s^2
Force = 30 N
Force = mass * acceleration
mass = force / acceleration
mass = 30 / 6
mass = 5 kg
At what point does a rubber band have the most elastic potential energy? Explain.
Answer:
You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy. ... When the rubber band is released, the potential energy is quickly converted to kinetic (motion) energy.

Explanation:
A rock is thrown with a force of 500 N and an acceleration is 75 m/s^2. What is its mass?
A. 575 kg
B. 3.8 x 104 kg
C. 0.15 kg
D. 6.7 kg
Answer:
We conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.
Hence, option D is correct.
Explanation:
Given
Force F = 500 NAcceleration a = 75 m/s²To determine
Mass m = ?
Important Tip:
The mass of a rock can be found using the formula F = ma
Using the formula
[tex]F = ma[/tex]
where
F is the force (N) m is the mass (kg) a is the acceleration (m/s²)now substituting F = 500, and a = 75 m/s² in the formula
[tex]F = ma[/tex]
[tex]500 = m(75)[/tex]
switch sides
[tex]m\left(75\right)=500[/tex]
Divide both sides by 75
[tex]\frac{m\cdot \:75}{75}=\frac{500}{75}[/tex]
simplify
[tex]m=\frac{20}{3}[/tex]
[tex]m=6.7[/tex] kg
Therefore, we conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.
Hence, option D is correct.

Explanation:
Took it on EDG 2021
Price can be defined as the amount of money that must be paid by a buyer (customer) to a seller (producer or owner), so as to acquire goods and services.
This ultimately implies that, it is an amount of money a customer that is buying goods and services are willing to pay to the seller (producer or owner) for the goods and services being offered.
In this scenario, we can deduce the following points:

What is the mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet?
0.3

27
Answer:
it would be 3
Explanation:
because you have to divide the length by the height of the incline.
The mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet will be 3.
What is the mechanical advantage?Mechanical advantage is a measure of the ratio of output force to input force in the system, it is used to obtain the efficiency of a mechanism.
The formula for the mechanical advantage of the inclined plane is found as;
[tex]\rm Mechanical \ advantage = \frac{length}{height} \\\\ Mechanical \ advantage =\frac{9}{3} \\\\ Mechanical \ advantage =3[/tex]
Hence the mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet will be 3.

A car moving with an initial velocity of 36 m/s slows down at a constant rate of -2.8 m/s^2 . What distance does the car travel after 3 seconds of deceleration? Remember to include units in your answer! *
Answer:
the distance covered by the car is 95.4 m.
Explanation:
Given;
initial velocity of the car, u = 36 m/s
acceleration of the car, a = -2.8 m/s²
time of motion of the car, t = 3 s
The distance covered by the car is calculated as;
s = ut + ¹/₂at²
s = 36(3) + ¹/₂ x (-2.8)(3)²
s = 108 - 12.6
s = 95.4 m
Therefore, the distance covered by the car is 95.4 m.

The force of the pulley is 652 newtons. It accelerates at 53 m/s. How much does the object weigh. a 1230 grams b 1.230 gram c 123.0 grams d 12.30 Grams
Answer:
d. 12.30 grams
Explanation:
Given the following data;
Force = 652 N
Acceleration = 53 m/s²
To find how much the object weigh, we would need to determine its mass;
Force = mass * acceleration
652 = mass * 53
Mass = 652/53
Mass = 12.30 grams.
Therefore, the object weighs 12.30 grams.
