If a 10Ω resistor is removed and replaced by a 20Ω resistor, at constant voltage, the current will decrease.

This law states that, the current flowing in a conductor is directly proportional to the voltage in the conductor.

V = IR

where;

I = V/R

At constant voltage, when the value of the resistance increases, the value of the current in the ciircuit wil decrease.

Thus, if a 10Ω resistor is removed and replaced by a 20Ω resistor, at constant voltage, the current will decrease.

Answer:calcite

Explanation:

Based on these observations, Calcite is the identity of this mineral sample. Therefore, the correct option is option C among all the given options.

Typically created by inorganic processes, a mineral is a naturally occurring homogenous solid having a specific chemical composition as well as a highly organized atomic arrangement. About 100 of the known mineral species—the so-called rock-forming minerals—make up the majority of the known mineral species, which number in the thousands.

A mineral is different from its laboratory-produced synthetic counterparts since it must by definition develop through natural processes. Based on these observations, Calcite is the identity of this mineral sample.

Therefore, the correct option is option C among all the given options.

Answer: 250kg m/s

Explanation: You multiply 50kg and 5m/s to get 250kg m/s

The momentum of the ball is 250 Kgm/s

Given the following data;

To find the momentum of the ball;

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. It is a vector quantity and as such has both magnitude and direction.

Mathematically, momentum is giving by the formula;

[tex]Momentum = mass\; * \; velocity[/tex]

Substituting into the formula, we have;

[tex]Momentum = 50 * 5[/tex]

Momentum = 250 Kgm/s

Therefore, the momentum of the ball is 250 Kgm/s

Answer:

s = 11.46 m

Explanation:

Since, the reaction time is 0.75 s. Hence, the brakes shall be applied after this time. So, the car will start to slow down after covering a distance at the constant speed during this time. This distance can be given as follows:

s = vt

where,

s = distance covered by car before slowing down = ?

v = speed of car = (55 km/h)(1 h/3600 s)(1000 m/1 km) = 15.28 m/s

t = reaction time = 0.75 s

Therefore,

s = (15.28 m/s)(0.75 s)

s = 11.46 m

5. Group A can be given the juice, Group B can be given the juice without the special ingredient

USE QUIZLET FLASH CARDS IT CAN HELP YOU WITH A LOT OF QUESTION

This suggests that the special juice did not have a positive impact on productivity, and it may even have had a negative effect.

To improve the experiment: Randomized assignment, Control group considerations, Double-blind design, Larger sample size.

1. Smithers' conclusion should be that the special juice did not increase the productivity of the workers. Group B, which did not receive the special juice, actually produced more stacks of paper (2,113 stacks) compared to Group A, which had the special juice (1,587 stacks).

2. To improve the experiment, Smithers could consider implementing the following:

a. Randomized assignment: Ensure that the assignment of workers to groups is done randomly. Random assignment helps minimize any potential bias or confounding variables that could affect the results.

b. Control group considerations: In this experiment, Group B serves as the control group since they did not receive the special juice.

c. Double-blind design: To eliminate potential biases, both the workers and the person assessing their productivity should be unaware of which group received the special juice.

d. Larger sample size: Increasing the sample size can enhance the statistical power of the study and improve the reliability of the results. With a larger sample size, any differences between the groups can be more confidently attributed to the intervention.

Answer:

This question appear incomplete

Explanation:

This question appear incomplete because of the absence of the time the honeybee spent while travelling from the hive. However, if we are to assume that the honeybee spent the same amount of time leaving/travelling as when it was returning. Then the formula to be used is

Speed = distance ÷ time

distance = speed × time

distance = 4 × 1

distance = 4 miles

To determine the displacement of the honeybee, the total distance covered by the honeybee in both to and fro journey will have to be summed (this is because displacement is a vector quantity).

Assuming the the speed and time spent while returning is the same with those spent while leaving, then the displacement will be distance × 2 (sum of all the distance covered)

Thus; 4 × 2 = 8 miles

Explanation:

Answer:

85.66m

Explanation:

Given the following data;

Horizontal velocity = 25.8m/s

Height = 54m

Initial velocity = 0

We would first of all, solve for the time taken using the formula for maximum height of a projectile.

H = ½gt²

Where;

We know that acceleration due to gravity is 9.8m/s²

Substituting into the equation

54 = ½*9.8t²

54 = 4.9t²

t² = 54/4.9

t² = 11.02

t = 3.32 secs

To find the distance;

Distance, x = velocity * time

x = vt

Substituting into the equation, we have;

x = 25.8*3.32

x = 85.66m

Answer:

t = 2.2 s

Explanation:

Given that,

Height of the roof, h = 24.15 m

The initial velocity of the pumpkin, u = 0

We need to find the time taken for the pumpkin to hit the ground. Let the time be t. Using second equation of kinematics to find it as follows :

[tex]h=ut+\dfrac{1}{2}at^2[/tex]

Here, u = 0 and a = g

[tex]h=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2\times 24.15}{9.8}} \\\\t=2.22\ s[/tex]

So, it will take 2.22 s for the pumpkin to hit the ground.

Answer:

the answer is D

Explanation:

To test the flow of electric current through a circuit we can use a lightbulb. If a current is generated the bulb will light with brightness. Thus, option D is correct.

An ammeter is an electric device used to measure the current through a circuit. The current in ampere, milliampere or microampere is recorded by the ammeter through the deflection of its needle.

A magnetic field is always associated with an electric field where, the fields will be right angled to each other. A moving magnet in turn causes an electric current like a moving charge make an electric current.

To light a bulb electrical energy is needed. Thus, we can  test the deflection in electric field using a a light bulb connected to the circuit. If there is a fine passage of electricity, the bulb will lighten. Thus, option D is correct.
