A car is travelling to the right with a speed of 40 m/s when the driver slams on the brakes. The car skids for 4 s with constant acceleration before it comes to a stop. What was the rate of the car's acceleration as it skidded to a stop?
Answer:
10m/s^2
Explanation:
Given data
velocity= 40m/s
time= 4 seconds
Acceleration a =????
We know that
a= velocity/time
substitute
a=40/4
a= 10m/s^2
Hence the acceleration will be 10m/s^2
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.

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:

A geologist sees a fault along which blocks of rock in the footwall have moved higher relative to blocks of rock in the hanging wall. What type of fault is this? Explain how you know.
Answer: Normal fault
Explanation:
The type of fault that is explained above is a normal fault. We should note that normal faults typically takes place in a divergent boundary in a scenario where the crusts may have been pulled apart.
Since the crust is pulled apart in this case, it leads to the downward movement of the hanging wall which leads to the football being above the hanging wall.
3. What is the difference between Synthetic Oil, Semi-Syntheic oil (Blend), High milage motor oil, and conventional motor oil?
Answer:
When evaluating synthetic blends, it's helpful to define the terms “synthetic blend” and “semi-synthetic”. Generally speaking, synthetic blends and semi-synthetic refer to the same thing: an oil that uses a combination of conventional and synthetic base oils in its formulation.

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.

what is the the relationship between velocity and gravity?
Answer: When objects fall to the ground, gravity causes them to accelerate.
Explanation: Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls.
What are the 2 types of ions.
Answer:
Anions have more electrons than protons and so have a net negative charge. Cations have more protons than electrons and so have a net positive charge. Zwitterions are neutral and have both positive and negative charges at different locations throughout the molecule.

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.

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.

What is the mechanical advantage of an inclined plane that has a length of 9 feet and a height of 3 feet?
0.3
3
6
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.

Many people love roller coasters. Some people call them scream machines. They agree that
riding a roller coaster is a thrilling experience. What you may not realize while you are going 60 miles an hour is that a roller coaster has no
engine. You are not being propelled around the track by a motor or pulled by anything. A roller coaster moves on its own. How do you think that
can happen?
Answer:
There is some sort of "rollers" on the trail part that is used to make the roller coaster move when it is going up. Then because of that, the speed gets quicker when it drops down, so then it could move for a longer time until it reaches the next arch.

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.
