Explanation:
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.
convert 35 km/h to m/s
14.Which of the following is TRUE of a body in equilibrium.
I. The sum of the forces in one direction is equal to the sum of the
forces in the opposite direction
II. The sum of the clockwise forces is equal to the sum of the
anticlockwise forces
III. The sum of the clockwise moments is equal to the sum of the anticlockwise moments
a) I only
b) II only
c) I and III only
d) I, II and III
Answer:
Explanation:
One
All three statements are saying exactly the same thing.
1. one direction forces = opposite direction forces. Note forces have direction. Always remember that forces have direction and you must always say what that direction is.
2. Two is saying the same thing as one. It is just that 2 is more specific about what the direction is. Clockwise is different from anti clockwise.
3. moments are forces and distances. Forces always have direction. Distances sometimes do not. At your level of study, I don't think it does. Later on, you will learn the word displacement which always has direction and that direction must be stated.
Answer D.
15 We are told to answer just 1 or 2 questions from the same student's posting. There are 4 here, so I'm going to give you just brief answers.
You should realize by now that a loaded bus has it's center of gravity raised. The answer is B
16 A is true.
Technically anything to do with turning is a torque.
D is also true.
C is better worded than B. I would pick B as the odd one out.
17
This is rotating so they must be on the same side of the pivot point. The moments add.
20*3 + 10*2 = 60 + 20 = 80 Newton Meters. Notice C has the right numbers associated with it, but the distance is divided into a Newton. Wrong answer.
In this series of questions, moments are defined as Force * Distance.
John attached a ball to a spring
Answer:
C down
Explanation:
The ball is pulling the spring down so this must be the direction of the force
What is the momentum of a 1, 500 kg car traveling at 3m/s?
67,500 kgm/s
67.5 kgm/s
4.5 kgm/s
4,500 kgm/s
========================================
Work Shown:
To find the momentum, we multiply the mass and the velocity.
m = mass = 1500 kg
v = velocity = 3 m/s
p = momentum
p = m*v
p = (1500 kg)*(3 m/s)
p = (1500*3) kg m/s
p = 4500 kg m/s
The momentum of an object is the product of its mass and velocity. Thus momentum of the car with 1500 kg and velocity of 3 m/s is 4500 kg m/s.
What is momentum?Momentum is a physical quantity that measure the ability to keep the force which make an object moves faster. Momentum like force is a vector quantity and is characterized with magnitude and direction.
Momentum is the product of velocity and its mass. Hence as the mass or velocity increases, momentum also increases. Increase in momentum makes the object moves faster.
Given mass of car = 1500 Kg
velocity = 3 m/s
momentum = velocity × mass
= 1500 Kg × 3 m/s
= 4500 Kg m/s.
Therefore, the momentum of the car is 4500 kg m/s.

tony walks at an average speed of 70 m/min from his home to his school.If the distance between his home and the school is 2100 , how much time does it take for tony to walk to school
It takes 30 minutes for Tony to get to school.
2100 divided by 70 is 30, which would represent the amount of minutes.
Also he is walking very fast to be getting 70 in a minute.
Hope this helps and have a nice day.

Their molecules move at the same average speed
Answer:
When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the objects.

Answer:
Coal is fossil fuel extracted from earth and since it takes a long time to replenish, it is called a non renewable source of energy
Explanation:
Coal is formed from the fossil fuel that lie deep beneath the earth crust . These fossil fuels are dead remains of living organism that burried beneath the earth crust million of years ago.
Coal is non renewable because if once it gets depleted it will take a very very long time to replenish.

A 5kg box rests on a table. a 3 kg box rests on top of the 5 kg box. what is the normal force from the table?
a. 19.6 n
b. 29.4 n
c. 49 n
d. 78.4 n
==> The total mass resting on the table is (5 kg + 3 kg) = 8 kg.
==> The total weight of that mass is (8 kg) x (9.8 m/s) = 78.4 newtons
==> The boxes are stacked. So the table doesn't know if the weight on it is coming from one box, 2 boxes, 3 boxes, or 100 boxes in a stack. The table only knows that there is a downward force of 78.4 newtons on it.
==> The table stands in a Physics classroom, and it soaks up everything it hears there. It knows that every action produces an equal and opposite reaction, and that forces always occur in pairs.
Ever since the day it was only a pile of lumber out behind the hardware store in the rain, the table has known that in order to maintain the good reputation of tables all over the world, it must resist the weight of anything placed upon it with an identical upward force. This is the normal thing for all good tables to do, up to the ultimate structural limit of their materials and construction, and it is known as the "normal force".
So the table in your question provides a normal force of 78.4 newtons. (d)
