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
Explanation:
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.

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.
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.

Write the equation which links kinetic energy, mass and speed. 5
(1 Point)
Answer:
KE = [tex]\frac{1}{2}[/tex] m[tex]v^{2}[/tex]
Explanation:
In the generation of energy from hydroelectric power station, the motion of water, and the turbines are paramount. The falling flowing water turns the blades of the turbine, which in-turn causes the movement of a coil within a strong magnetic field.
The motion of the coil which cuts the strong magnetic field induces current. Thus, the system generates electrical energy.
The equation that links kinetic energy (KE), mass (m) and speed (v) can be expressed as:
KE = [tex]\frac{1}{2}[/tex] m[tex]v^{2}[/tex]

Increasing an object's height also results in an increase of the object'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.
The correct answer is B.

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.
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.
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.

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
