A 50 kg ball rolls down the street at 5 m/s.
Calculate the momentum of the ball.
Answer: 250kg m/s
Explanation: You multiply 50kg and 5m/s to get 250kg m/s
The momentum of the ball is 250 Kgm/s
Given the following data;
Mass = 50 kgVelocity = 5 m/sTo find the momentum of the ball;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. It is a vector quantity and as such has both magnitude and direction.
Mathematically, momentum is giving by the formula;
[tex]Momentum = mass\; * \; velocity[/tex]
Substituting into the formula, we have;
[tex]Momentum = 50 * 5[/tex]
Momentum = 250 Kgm/s
Therefore, the momentum of the ball is 250 Kgm/s

A magnet placed against the wall of a metal shed falls to the ground, where it attracts a nail. What is the most likely explanation for this observation?
The wall is the opposite pole from the magnet.
The shed is not made of iron or steel.
The magnet is not magnetized.
The nail pulled the magnet to the ground.
Answer:
the answer is B but I'm not completely sure
The reason for this observation is that the shed is not made of iron or steel.
The special magnetic property of iron is called ferromagnetism. As a result of this special magnetic property, iron can be attracted easily by a magnet. Steel is made from iron so it is also highly magnetic.

Smithers thinks that a special juice will increase the productivity of workers. He creates
two groups of 50 workers each and assigns each group the same task (in this case,
they're supposed to staple a set of papers) Group A is given the special juice to drink
while they work, Group B is not given the special juice. After an hour, Smithers counts
how many stacks of papers each group has made. Group A made 1,587 stacks, Group
B made 2,113 stacks
What should Smithers conclusion be?
How could this experiment be improved?
Answer:
1. Group B
2. The juice
3. The number of stacks of paper
4. the juice did not help improve a quicker process
5. Group A can be given the juice, Group B can be given the juice without the special ingredient
USE QUIZLET FLASH CARDS IT CAN HELP YOU WITH A LOT OF QUESTION
This suggests that the special juice did not have a positive impact on productivity, and it may even have had a negative effect.
To improve the experiment: Randomized assignment, Control group considerations, Double-blind design, Larger sample size.
1. Smithers' conclusion should be that the special juice did not increase the productivity of the workers. Group B, which did not receive the special juice, actually produced more stacks of paper (2,113 stacks) compared to Group A, which had the special juice (1,587 stacks).
2. To improve the experiment, Smithers could consider implementing the following:
a. Randomized assignment: Ensure that the assignment of workers to groups is done randomly. Random assignment helps minimize any potential bias or confounding variables that could affect the results.
b. Control group considerations: In this experiment, Group B serves as the control group since they did not receive the special juice.
c. Double-blind design: To eliminate potential biases, both the workers and the person assessing their productivity should be unaware of which group received the special juice.
d. Larger sample size: Increasing the sample size can enhance the statistical power of the study and improve the reliability of the results. With a larger sample size, any differences between the groups can be more confidently attributed to the intervention.

What happens to the current in a circuit if a 10Ω resistor is removed and replaced by a 20Ω resistor? (voltage stays the same)
Current will increase
Current will not travel through the circuit
Current will stay the same
Current will decrease
If a 10Ω resistor is removed and replaced by a 20Ω resistor, at constant voltage, the current will decrease.
Ohms lawThis law states that, the current flowing in a conductor is directly proportional to the voltage in the conductor.
V = IR
where;
V is the voltage of the conductotI is the currentR is the resistanceI = V/R
At constant voltage, when the value of the resistance increases, the value of the current in the ciircuit wil decrease.
Thus, if a 10Ω resistor is removed and replaced by a 20Ω resistor, at constant voltage, the current will decrease.

Which of the following objects will have the greatest inertia?
Question options:
10 m
10 J
10 N
10 kg
Answer:
The proximate answer pertaining to your question entails 10 kg.
Justification:
The statement implies which of the following units preceded by the value of 10 will obtain substantial inertia.
Exploiting conversions, this can be evinced/demonstrated:
Choice "10 m" => .01 kg
10 J ==> 0.10
10 N ==> 1.02 kg
10 kg ==> 10 kg
Thus, an object obtaining a cumulative mass of 10 kg obtains substantial inertia.

Student A says electric motors use the forces between electromagnets to make something start turning. Student B says electric motors use magnets moving near coils of wire to create a current in the wire. Which student is correct?
Answer:
Student A is correct.
Explanation:
An electromagnet can be defined as the magnet that is produced by the electric current passing through a wire surrounding a metal piece. In an electric motor, magnets surrounds the the coil carrying currents. Because of the magnetic field, the current carrying coil experiences a force and it starts to rotate. Thus the electric motors uses the forces between the electromagnets to start running.
Therefore, student A is correct.
A ball is thrown horizontally at 25.8m/s from 54 meter high cliff. How far from the base of the cliff does the ball land?
Answer:
85.66m
Explanation:
Given the following data;
Horizontal velocity = 25.8m/s
Height = 54m
Initial velocity = 0
We would first of all, solve for the time taken using the formula for maximum height of a projectile.
H = ½gt²
Where;
H is the maximum height measured in meters. g represents the acceleration due to gravity measured in meters per seconds square. t represents the time taken measured in seconds.We know that acceleration due to gravity is 9.8m/s²
Substituting into the equation
54 = ½*9.8t²
54 = 4.9t²
t² = 54/4.9
t² = 11.02
t = 3.32 secs
To find the distance;
Distance, x = velocity * time
x = vt
Substituting into the equation, we have;
x = 25.8*3.32
x = 85.66m

You are driving down a street in a car at 55 km/hr. Suddenly, a child runs into the street. If it takes you .75 s to react and apply the brakes, how many meters will you have moved before you begin to slow down?
Answer:
s = 11.46 m
Explanation:
Since, the reaction time is 0.75 s. Hence, the brakes shall be applied after this time. So, the car will start to slow down after covering a distance at the constant speed during this time. This distance can be given as follows:
s = vt
where,
s = distance covered by car before slowing down = ?
v = speed of car = (55 km/h)(1 h/3600 s)(1000 m/1 km) = 15.28 m/s
t = reaction time = 0.75 s
Therefore,
s = (15.28 m/s)(0.75 s)
s = 11.46 m
