Total distance does not take into account the direction of the object, but displacement always includes direction.
Question 1 options:
True
False
Answer: True
Explanation:
Distance is a scalar, which means it has no direction. It is the sum of the entire path traveled.
Displacement is a vector, which means it does have direction. It is the shortest path from the start to the end. It is defined as [tex]x_f-x_i[/tex].

Answer:
newton's first law of motion
Explanation:
this is because newton's first law of motion states that every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it so...
isn't this similar to the law of inertia?

A marble on a frictionless track, starting from point A in the drawing, is projected down the curved runway. (This means that the initial speed of the particle is NOT zero!) Upon leaving the runway at point B, the particle is traveling straight upward and reaches a height of 5.00 m above the floor before falling back down. Ignoring air resistance, find the initial speed of the particle (v0) at point A.
Answer:
v = 4.4 m / s
Explanation:
Unfortunately, the exercise scheme does not appear. Let's analyze the problem the marble leaves point A with an initial velocity, goes down and then rises to a given height where its velocity is zero, in the whole trajectory they tell us that the resistance is zero, so we can use the conservation relations of the enegy.
Starting point. Point A
Em₀ = K + U = ½ m v2 + mg y_a
point B.
Em_f = U = m g y
the energy is conserved
Em₀ = Em_f
½ m v² + mg y_a = m g y
½ m v² = m g (y -y_a)
v = [tex]\sqrt {2g ( y - y_a)}[/tex]
In the exercise the diagram is not seen, but the height of point A must be known, suppose that y_a = 4 m
v = [tex]\sqrt{ 2 \ 9.8 ( 5 -4)}[/tex]
v = 4.4 m / s
calculate capacitance if Q=7mc and delta V=12V
Answer:
Capacitance = 0.00058 Farads
Explanation:
Given the following data;
Charge, Q = 7mC to Coulombs = 7/1000 = 0.007C
Velocity = 12V
To find the capacitance;
Capacitance = charge/potential difference
Substituting into the equation, we have;
Capacitance = 0.007/12
Capacitance = 0.00058 Farads
A student runs up a flight of stairs which info is not needed to calculate the rate of the student is doing work against gravity A the height of the flight of stairs B the length of flight of stairs C the time taken to run up the stairs D the weight of the student
Answer:
B.
Explanation:
Given that a student runs up a flight of stairs which info is not needed to calculate the rate of the student is doing work against gravity A the height of the flight of stairs B the length of flight of stairs C the time taken to run up the stairs D the weight of the student
The rate of doing work is known as power.
Power = work done/time
Work done = energy = mgh
Since energy = mgh
Where mg = weight
And h = height
Time = time taken to run up the stairs.
Time, weight mg and height h will be needed while the Length of the flight is therefore not needed.

In which scenario does radiation occur? warming soup on a stove drying towels at the beach cooking eggs in boiling water warming a sore muscle with a hot pack
Answer: drying towels at the beach.
Explanation:
Radiation simply has to do with the energy that is gotten from a particular source and then goes through some materials. It simply means the way energy is being transmitted as waves or heat through a certain medium.
From the options given, the scenario whereby a radiation takes place is when drying towels on the beach.
Answer:B-drying towels at the beach

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.

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.

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.
Total distance does not take into account the direction of the object, but displacement always includes direction.

Which of the following is true regarding transverse waves?
A. They only occur when the medium is a solid.
B. The directions that energy and matter travel in are parallel.
C. A hockey puck moving forward and spinning on ice is an example of a transverse wave.
D. The directions that energy and matter travel in are perpendicular to one another.
The true statement regarding the transverse waves should be option D. the direction at which the energy and the matter should be travel in the perpendicular direction.
What are transverse waves?It is the waves where the motion in which all the points should be on the wave oscillate along the paths at the right angles with respect to the wave of the direction. The example of this kind of waves should be electromagnetic, etc. In this, the directions where the energy and the travel of matter should be perpendicular to each other
Hence, the correct option is d.

For any object in motion, distance is always _________ displacement
Answer:
for any object in motion , distance is always greater than displacement
For any object in motion, distance is always greater or equal to the displacement but it can never be less than the displacement because displacement is the shortest distance measured between the initial and the final position.
What is displacement?An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard.
Displacement describes this shift in location.
Distance is always higher or equal to displacement for any item in motion, but it can never be less because displacement is the shortest distance between the beginning and end positions.

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.
