D. The voltage and resistance would be the same.
How a light bulb in a circuit with a battery works?If the light bulbs are connected in parallel, the current flowing through the light bulbs combine to form the current flowing in the battery, while the voltage drop is 6.0 V across each bulb and they all glow.
In a series circuit, every device must function for the circuit to be complete.
Electricity needs a path to follow to get from one destination to another. And the journey is always the same:
Power – Electricity always starts from a source, like a battery or an outlet.
A battery is a device that converts chemical energy contained within its active materials directly into electric energy by means of an electrochemical oxidation-reduction (redox) reaction.
This type of reaction involves the transfer of electrons from one material to another via an electric circuit.
In electronics, a circuit is a complete circular path that electricity flows through. A simple circuit consists of a current source, conductors and a load.
The term circuit can be used in a general sense to refer to any fixed path that electricity, data or a signal can travel through.
Therefore,
If the switch were replaced with a section of wire ,the voltage and resistance would be the same.

a. What is the coefficient of kinetic friction?
Explanation:
Coefficient of kinetic friction is the resistive force that opposes the motion of a body as it moves and is in contact with another body.
It is found by dividing the frictional force by the normal force.
Friction is a force that opposes motion. Static friction is for bodies that are not in motion Kinetic friction is for moving bodies.Abby is 5 feet tall and casts a 4 foot long shadow of her older brother Ethan is standing next to her and casts a 4.6 shadow how much taller than Abby us Ethan

During a basketball game, a player moves forward 6 meters, backwards 3 meters, and then forward 7 meters over the span of 12 seconds. What is the player's average velocity?
A. 0.83 m/s backward
B. 1.33 m/s backward
C. 0.83 m/s forward
D. 1.33 m/s forward
Answer:
0.83m/s forward
Explanation:
Velocity is the displacement divided by time.
Velocity = [tex]\frac{displacment}{time}[/tex]
Displacement is the distance moved in a specific direction;
→ 6meters forward
← 3meters backwards
→ 7 meters forward
Net displacement =7m + 3m = 10m forward
So;
Velocity = [tex]\frac{10}{12}[/tex] = 0.83m/s forward

Explanation:
The direction of a moving object will not change if the net force acting on it is
Answer:
The direction of a moving object will not change if the net force acting on it is zero.
Explanation:
If there is a net force acting on a body, the body may accelerate, slow down, or change direction. In other words, an unbalanced net force may change the state of motion of a body.
The only way a moving object will not change its direction if the body is moving with a constant velocity, meaning all the forces acting on the body are in equilibrium (or balanced). In other words, the net force acting on it is zero, and the speed, as well as direction, would not change.
Therefore, we conclude that the direction of a moving object will not change if the net force acting on it is zero.
Suppose a rollerblade racer finnished a 132 meter race in 18 seconds. What is the average speed of the rollerblade racer
Answer:
As = 7.33 [m/s]
Explanation:
To solve this problem we must use the definition of the average speed, which is equal to the relationship between the distance over time.
As = x/t
where:
As = average speed [m/s]
x = distance = 132 [m]
t = time = 18 [s]
As = 132/18
As = 7.33 [m/s]

A student sits on the roof of their house which is 16 meters high. She can launch water balloons (horizontally) from a slingshot at 26 m/s. How far will each balloon travel (horizontally)?
A. 67.06 m
B. 17.06 m
C. 0.06 m
D. 47.06 m
Answer:
The horizontal distance traveled by the water balloons is 47.06 m.
D. 47.06 m
Explanation:
Given;
height of the house, h = 16 m
horizontal velocity of the water balloons, v = 26 m/s
The time taken for the water balloons to hit the ground is given by;
[tex]t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2*16}{9.8} }\\\\t = 1.81 \ s[/tex]
The horizontal distance traveled by the water balloons is given by;
x = vt
x = 26 x 1.81
x = 47.06 m
Therefore, the horizontal distance traveled by the water balloons is 47.06 m.

A scientist has two radioactive substances. One emits beta particles, and the other emits alpha particles. He thinks that since the alpha particles are larger, they are more dangerous to humans. Is he correct? Why or why not?
No, because beta particles move faster and can penetrate into the human body more easily.
No, because neither type of particle is dangerous to humans.
Yes, because alpha particles move more slowly, and therefore leave more lasting damage to humans.
Yes, because the larger particles carry more energy and can cause more damage to cells.
Answer:
No, because beta particles move faster and can penetrate into the human body more easily.
Explanation:
Some beta particles are capable of penetrating the skin and causing damage such as skin burns. However, as with alpha-emitters, beta-emitters are most hazardous when they are inhaled or swallowed.

Calculate the wave speed for a wave with a wavelength 2m and frequency of 0.3 Hertz?V
wavelength X frequency
Answer:
0.6m/s
Explanation:
Given parameters:
Wavelength = 2m
Frequency = 0.3hz
Unknown:
Speed of the wave = ?
Solution:
To find the speed of the wave, we must understand that this parameter depends on the frequency and wavelength of the wave.
So;
V = f∧
F is the frequency
∧ is the wavelength
Now, insert the parameters and solve;
V = 0.3 x 2 = 0.6m/s
