If the change in velocity increases, the acceleration during the same time period increases as well. The correct option is B.

Electric current is the flow of electric charge through a conducting material, such as a wire. It is measured in units of amperes (A), which represents the rate of flow of electric charge.

The standard definition of electric current is that it is the amount of electric charge passing through a given area of a conductor in unit time.

Mathematically, electric current is expressed as:

I = Q / t

Where

I = the electric current,

Q =the amount of electric charge that flows through a conductor,

t = the time interval during which the charge flows.

The unit of electric charge is coulombs (C), which represents the charge carried by a current of one ampere flowing for one second. So, one ampere of electric current represents a flow of one coulomb of electric charge per second.

Electric current is typically measured using an ammeter, which is a device that is inserted in series with a circuit to measure the current flowing through it. The ammeter is designed to have very low resistance, so it does not significantly affect the current flowing through the circuit being measured.

Here in the question,

If the change in velocity increases, the acceleration during the same time period increases as well. This is because acceleration is directly proportional to the change in velocity over time, as expressed by the formula:

a = (v_f - v_i) / t

Where

a = acceleration,

v_f = the final velocity,

v_i = the initial velocity,

t = the time interval during which the velocity changes.

If the change in velocity is greater, the numerator of the equation is larger, and therefore, acceleration is greater. Similarly, if the time interval is kept constant, an increase in velocity change leads to an increase in acceleration.

Therefore, when velocity increases the acceleration also increases.

Answer:

Time, I believe. Pretty sure it's time lol

Answer:

35.14 m/s

Explanation:

The Law of Conservation of Momentum states that the momentum before and after a collision is the same.

Let's set the ball to have the subscript of 1 and the man to have the subscript of 2.

The initial and final mass of the ball is the same, so m₁ = 7.00 kg on both sides of the equation.

The initial velocity of the ball, v₁ on the left side of the equation, is the unknown variable we are trying to find.

The initial and final mass of the man is the same, so m₂ = 75.0 kg on both sides of the equation.

The man starts at rest, meaning that his initial velocity is v₂ = 0 m/s on the left side of the equation.

The final velocity of both the ball and the man is 3.00 m/s, so we can set v₁ and v₂ on the right side of the equation to equal 3.00 m/s.

Left side of the equation:

Right side of the equation:

Substitute these values into the Law of Conversation of Momentum formula.

Multiply and simplify.

Divide both sides of the equation by 7.

The ball needs to be moving at a speed of 35.14 m/s in order to send the man off at a speed of 3.00 m/s.

Answer:

b. -1.5 m/s²

Explanation:

Given the following data;

Initial velocity = 15m/s

Time = 10 seconds.

Since the car came to rest, final velocity = 0m/s

To find acceleration;

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of final speed from the initial speed all over time.

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{initial \; speed - final \; speed}{time}[/tex]

[tex]a = \frac{v - u}{t}[/tex]

Where,

a is acceleration measured in [tex]ms^{-2}[/tex]

v and u is initial and final speed respectively, measured in [tex]ms^{-1}[/tex]

t is time measured in seconds.

Substituting into the equation, we have;

[tex] Acceleration, a = \frac{0 - 15}{10}[/tex]

[tex] Acceleration, a = \frac{-15}{10}[/tex]

Acceleration = -1.5 m/s²

Answer:

The final temperature of the bath water will be 55°C

Explanation:

A student is preparing to take a bath when she realizes that the hot water tap is not working.

The student goes to the kitchen and prepares 10 L of 100 degree Celsius water to mix with 10 L of 10 degree Celsius water. What will be the final temperature of the bath water?

Using the relation, Heat lost  = Heat gained (assuming no heat is lost to the surroundings).

Heat lost by hot water = heat gained by cold water

Using the formula of heat, Q = mcΔT

where m = mass of water, c = specific heat capacity of water, ΔT = temperature difference

mass of water = density * volume (density of water = 1 kg/L)

mass of hot water, m₁ = 1 kg/L * 10 L = 10 kg;

mass of cold water, m₂ = 1 kg/L * 10 L = 10 kg;

specific heat capacity of water, c = 4200 j/kg

Let the final temperature of the mixture be T

-m₁cΔT₁ = m₂cΔT₂ ( since heat is lost by the hot water)

-m₁ΔT₁ = m₂ΔT₂

-10 * (T- 100) = 10 * (T - 10)

-10T + 1000 = 10T - 100

20T = 1100

T = 1100/20

T = 55°C

Therefore, the final temperature of the bath water will be 55°C

Answer:

1) Ex(P) = -8.34602 N/C

2) [tex]E_y(P)[/tex] = -5.23850174216 N/C

3) Question (3) is a similar question to (1)

4) [tex]E_y(P)[/tex] = -5.23850174216 N/C

5) [tex]\sigma _b[/tex] ≈ 1.041466 C/m²

6) σₐ ≈ 2.2330413 C/m²

Explanation:

The given parameter of the point charge located at the center of a conducting shell

The charge of the point charge, q₁ = -8.9 μC

The inner radius of the shell, a = 2.8 cm

The outer radius of the shell, b = 4.1 cm

The charge of the conducting shell, q₂ = 2.2 μC

Therefore, we have;

1) The point P(8.5, 0)

[tex]V = k \cdot \dfrac{q_1 + q_2 }{r^2}[/tex]

By plugging in the values, we have;

For

R₁ < R₂ < r, for the electric field at the point, 'P', we have;

[tex]E_x(P) = 9 \times 10^9 \times \dfrac{-8.9 \ \times 10^{-6} + 2.2 \ \times 10 ^{-6} }{(0.085 \ )^2} = -8.34602[/tex]

Ex(P) = -8.34602 N/C

2) For the point given with coordinates (8.5, 0), the distance of the y-component of point from the center = 0

The y-component of the electric field = 0 N/C

4) For r = 1.4 cm, along the y-axis we have;

R₁ < r < R₂

Therefore, we have;

[tex]E = k \cdot \left( \dfrac{q_1 }{r} + \dfrac{q_2}{R_2}\right)[/tex]

Substituting the values, we get;

[tex]E_y(P) = 9 \times 10^9 \times \left( \dfrac{-8.9 \times 10^{-6}}{0.014} + \dfrac{2.2 \times 10^{-6}}{0.041}\right) = -523850174216[/tex]

[tex]E_y(P)[/tex] = -5.23850174216 N/C

5) The charge density, [tex]\sigma _b[/tex], is given as follows;

[tex]\sigma_b = \dfrac{Q}{A} = \dfrac{2.2 \times 10^{-6} }{4\times \pi \times 0.041^2 } \approx 1.041466 \ C/m^2[/tex]

6) Similarly, we have;

[tex]\sigma_a = \dfrac{Q}{A_a} = \dfrac{2.2 \times 10^{-6} }{4\times \pi \times 0.028^2 } \approx 2.2330413 \ C/m^2[/tex]

Warming signs before fad diet includes:

1. When a special type of diet is recommended for weight loss.

2. When quick weight loss is promised instead of advice on the need to exercise, eat healthy foods including fruits and vegetables, and adopt a good feeding behavior.

3. Promises rapid weight loss in a short period of time.

After taking the fad diet the following might be experienced:

1. Constipation.

2. Weakness and fatigue.

3. More accumulation of fats in the body in the long run after a short term normal  BMI (Body mass index).

4. Lower metabolic rates over time.

Explanation:

weight loss is a practice adopted by people for various reasons ranging from the desire to stay healthy to, ability to pursue a career that requires a good Body Mass Index. For instance, A BMI (Body mass index) which is equal to a person's weight (kg) / (height(m))^2 of 30 and higher is considered obese.

Fad diet which may give a temporary result of weight loss is not considered totally healthy as it doesn't capture the need to eat a healthy balanced diet instead focuses on more routine consumption of a particular kind of diet.

A healthy weight loss plan captures the need to exercise, reduce body fats while eating healthy. Eating fruits, vegetables are also encouraged.
