Answer:
Technician B
Explanation:
An engine can be disabled by removing the fuel pump fuse or relay if equipped. Therefore, Technician B is correct.
What can make an engine stop working?Engines generally stop suddenly if they suffer from a lack of fuel or sparks. An engine that can stop dead without prior warning and has probably had an instant ignition failure although when it locks solid it's more probably to have seized.
There are two ways to stop a diesel engine, remove the fuel pump fuse or cut off the fuel or the air. The easy way to stop a boat engine is to cut off the air.
The most general reasons for poor engine combustion because of broken valve seals, overused piston rings, holes within cylinders, and forcing air to leak out.
Assuming it's a gasoline-powered vehicle when removing a fuse or breaker for the ignition or fuel injection, the car wouldn't start. An engine can be disabled by cutting off the fuel pump fuse or relay if equipped.

Which is always true in a closed system?
Acceleration is not constant.
Mass is not conserved.
Momentum is conserved.
Velocity is constant.
Answer:
The correct option is momentum is conserved
Explanation:
A closed system is a system that is independent/free of external factors/force and does not exchange matter with its surrounding. Since a close system is free of external factors/force; acceleration is constant in it, mass is conserved in it and there will be changes in velocities of objects in the closed system.
This question actually seeks to test our knowledge of the law of momentum. The law of conservation of momentum states that the momentum of a closed system is conserved.
C: Momentum is consevered

Which of the following functions would be most immediately inhibited in the insects' cells?
Choose 1 answer:
(Choice A) A Protein synthesis
(Choice B) B DNA replication
(Choice C) C Photosynthesis
(Choice D) D Cell division
Answer:
protein synthesis
Explanation:
A pesticide kills insects by disabling the ribosomes in their cells. The function that would be most immediately in the insects' cells is protein synthesis. The correct option is A.
What are pesticides?Pesticides are the chemicals that are used to kill insects and other microbes that infect the crops and other things. Pesticides are very harmful for health of other animals and humans. They also cause disabilities in birds which eat the insects killed by pesticides.
Protein synthesis is a process of synthesizing protein in the cell. This process done by cell organelles and DNA and RNA. Pesticides degenerate the process of protein synthesis in insects, they eventually die due to no working of cell.

A load of 800 N is lifted using a block and tackle having 5 pulleys. If the applied effort is 200 N, calculate
i. Mechanical advantage
ii. Velocity ratio
iii. Efficiency
iv. Output work if load is lifted 5m high.
v. Input work
Explanation:
Load=800N
Effort=200N
1. Mechanical Advantage = LOAD/EFFORT
= 800N/200N
= 4
2 Velocity Ratio = no. Of pulleys =5
3. Efficiency = Mechanical advantage / velocity ratio × 100%
= (4/5)×100%
=80%
4. output work= load×load distance
= 800N × 5m
= 4 × 1000J
5. Efficiency = (output work/input work) ×100%
Or, 80% = (4000J/input work) ×100%
Or, 80%/100% = 4000J/inputwork
Or, 4/5 = 4000J/inputwork
Or, input work =4000J × 5/4
Input work = 5×1000J

When a beam of light is incident on a surface, it delivers energy to the surface. The intensity of the beam is defined as the energy delivered per unit area per unit time.
What is the unit of intensity, expressed in SI base units?
Answer:
Kg
Explanation:
Given that the definition of intensity is:
The intensity of the beam is defined as the energy delivered per unit area per unit time. That is,
I =( E × t)/A
Which can expressed as
I = J/m^2/s
The S.I Units of
Energy is Joule = kgm^2s^-1
Area A = m^2
Time t = s
Intensity I = kgm^2s^-1 × m^-2 × s
Intensity I = kg
The cubic metres and seconds are cancelled out
Therefore, the S.I units of intensity is kg

a. Opposite charges attract/repel each other, which means a Positive charge from a
proton/electron will attract/repel negative charge from an electron.
Answer:
Opposite charges attract each other, which means that a positive charge from a proton will attract negative charge from an electron.
Explanation:
Opposite charges attract because because their forced act in the same direction, which pulls them together. Protons are always positively charged subatomic particles and electrons are negatively charged subatomic particles. This attraction between the protons and electrons in atoms is what enables them to stay together and bond with other atoms.

Astronauts who traveled to the moon were able to float slightly as they walked along its surface. Why were the astronauts able to do this? The weight of the astronaut on Earth is less than his weight on the moon. The mass of the astronaut on Earth is less than his mass on the moon. The weight of the astronaut on Earth is greater than his weight on the moon. The mass of the astronaut on Earth is greater than his mass on the moon.
Answer: The weight of the astronaut on earth is greater than his weight on the moon.
Explanation:
The reason I got this answer is because the astronaut will have the same mass on the moon as he does on earth. Also the weight of a person or object is determined by gravity. So since the moons gravity isn’t as strong as earths gravity the astronauts are lighter in terms of weight, and this is how they slightly float.
The weight of the astronaut on Earth is greater than his weight on the Moon. The third option is correct.
What is gravity?The force of attraction felt by a person at the center of a planet or Earth is called as the gravity.
The Earth has the acceleration due to gravity, g = 9.81 m/s², Moon has the acceleration due to gravity 6 times less than that of Earth.
Astronauts who traveled to the Moon were able to float slightly as they walked along its surface. The astronauts were able to do this because they have the same mass on the Moon as he does on Earth.
The weight of a person or object is determined by gravity. Since, the Moon's gravity isn’t as strong as Earth's gravity. So, the astronauts slightly float on Moon.
The weight of the astronaut on Earth is greater than his weight on the moon.

Answer:
then you solve two torque one is anticlockwise and one is clock wise toque 1=force*perpendicular distance is equal to torque 2= force* perpendicular distance so tau = torque 1+ torque 2and give your answer
Answer:
W = 4 N (to balance the beam)
Explanation:
take moment at support Δ
∑M at Δ = 0 (note: clockwise is + and counter clockwise is - )
0 = W(100 - 30) + 2(60-30) + 1(50-30) - 12(30)
0 = W70 + 2(30) + 1(20) - 360
0 = W70 + 60 + 20 - 360
0 = W70 - 280
280 = W70
W = 280 / 70
W = 4 N (to balance the beam)
to take the reaction at support Δ
Δ = 12 + 1 + 2 + 4
Δ = 19 N
proof that W = 4
∑M at 12N = 0
0 = 19(30) - 1(50) - 2(60) - W(100)
0 = 570 - 50 - 120 - 100W
100W = 400
W = 400 / 100
W = 4 N -------- ok
If the toy helicopter weighs 115 N and is hovering motionless in the air, which of these options MOST accurately describes the force that the helicopter's propeller must exert?
Answer:
If the helicopter is not moving, then it is not being accelerated.
By second Newton's law we have that:
F = m*a
Force equals mass times acceleration.
Then if we do not have acceleration, we have:
F = m*a = m*0 = 0.
Then the total force must be zero.
So if the gravitational force (pulling down) is 115N, then the force of the propeller must be such that:
Total force = F - 115N = 0
F = 115N
The force of the propeller must be also of 115N, but in the opposite direction.
