Explanation:

Answer:

3080

Explanation:

Potential energy is the energy stored or contained in a body as a result to its relative position to other objects, an example is an object that is placed at a height above the ground thereby experiencing gravitational energy.

Potential energy = mass × gravity × height

Given that: height = 11.08 m, gravity = 9.81 m/s² and mass = mass of boy + mass of ball = 25.1 + 2.94 = 28.34 kg

Potential energy =28.34 × 9.81 × 11.08 = 3080

This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.

"Ampere" means "coulomb per second".

Answer:

Ep = 0.6095 [J]

Explanation:

As defined in the problem statement, potential energy is defined as the product of mass by gravity by height. But first we must convert all the values given to measures of the international system (SI)

g = gravity = 10 [m/s^2]

h = elevation = 40 [ft] = 12.19 [m]

m = mass = 5 [g] = 0.005 [kg]

Ep = potential energy [J]

Ep = 0.005*10*12.19 = 0.6095 [J]

Answer:

640 m.

Explanation:

The following data were obtained from the question:

Acceleration (a) = –20 m/s/s

Time (t) = 8 s

Final velocity (v) = 0 m/s

Distance (s) =.?

Next, we shall determine the initial velocity (u) of the car. This can be obtained as follow:

Acceleration (a) = –20 m/s/s

Time (t) = 8 s

Final velocity (v) = 0 m/s

Initial velocity (u)

a = (v – u) / t

–20 = (0 – u) / 8

–20 = – u / 8

Cross multiply

–20 × 8 = – u

– 160 = – u

Divide both side by – 1

u = – 160 / – 1

u = 160 m/s

Finally, we shall determine the distance travelled by the car before stopping as follow:

Time (t) = 8 s

Final velocity (v) = 0 m/s

Initial velocity (u) = 160 m/s

Distance (s) =.?

s = (v + u)t /2

s = (0 + 160) × 8 /2

s = (160 × 8) /2

s = 1280 / 2

s = 640 m

Therefore, the car travelled 640 m before stopping.

Explanation:

Density can be found by dividing the mass by the volume.

[tex]d=\frac{m}{v}[/tex]

The mass is 20 grams.

We have to find the volume.

[tex]m= 20 \ g\\v= 30 \ cm^3[/tex]

Substitute the values into the formula.

[tex]d=\frac{20 \ g}{30 \ cm^3}[/tex]

Divide.

[tex]d=\frac{2}{3} \ g/cm^3[/tex]

[tex]d= 0.666666667 \ g/cm^3[/tex]

The density is 2/3 grams per cubic centimeter.

The acceleration of the object is determined as -2.5 m/s².

Acceleration is the rate of change of velocity with time.

Mathematically, acceleration is given as;

a = Δv/Δt

a = (v₂ - v₁)/(t₂ - t₁)

where;

From the graph;

the initial velocity = 40 m/s

the final velocity = 10 m/s

the final time = 12 seconds

the initial time = 0 second

acceleration = (10 - 40) / (12 - 0)

acceleration = -30/12

acceleration = -2.5 m/s²

Thus, the acceleration of the object is determined as -2.5 m/s².

scatter plots show the relationship between the independent and dependent variables

Explanation:

A scatter plot is a graph which shows two variables plotted along two axes (usually the x and y axes). Scatter plots are useful in establishing any form of correlation between the dependent and independent variables in any study.

Correlation simply means the degree of relationship between variables, that is, how much does one variable affect the other? When scatter plots are almost a straight line graph, there is a high correlation between the variables. When the points in a scatter plot are isolated, there is little (sometimes zero) correlation between the variables.

ecosystem; hurricanes and tornadoes; catastrophic events.; Fooding; moving water; soil

Explanation:

After using the word bank to fill in the blanks in the passage, the passage reads;

"The organisms and environments that make up a community called an ecosystem are constantly changing. Sudden and violent events, such as hurricanes and tornadoes that often cause these changes are called catastrophic events. Fooding results when rainfall exceeds the holding capacity of a drainage system. The energy of the  fast-moving water and the layers of sediment carried by it  can uproot or bury plants, reshape the soil and destroy  roads and buildings."

The property of air which makes it effective in protecting firefighters is that it is a poor thermal conductor.

We define air as a mixture of gasses. We know that there a re several gases that are known to compose air and among these are oxygen, carbon dioxide, noble gasses and nitrogen.

We know that air is a poor conductor of heat. As such, air does not heat up quite easily and this would help to protect the fireman from getting burnt since air does not easily allow heat to pass through it as it were, this is why the firefighters depend on the insulative property of air.

Answer:

Explanation:

In this unit of measurement for distance or length, the units are arranged from the least to the largest unit i.e

mm < cm < m < km

Where mm is millimeter, cm is centimeter, m is meter and km is kilometer.

Hence, the appropriate unit to be used depends on how small or wide the length/distance being referred to is. For instance, the length of a stapler pin should be measured in millimeter while the length of a pen should be measured in centimeter. The appropriate measurement can be determined by determining the closest unit the value falls into. For instance, there is no need to refer to a length as 1000 cm when it can be referred to as 10 m (since 100 cm equals 1 m)

1. Width of a physics book should be measured in centimeters (this is similar to length of a pen).

2. Distance from New York to Utah should be measured in kilometers (Distance between far cities or states are measured in kilometers).

3. Length of a fingernail should be measured in millimeters (this is similar to the length of a stapler pin)

4. Length of hallway should be measured in meters (This is generally larger than centimeter but lesser than kilometer)

5. Height of a mountain should be measured in kilometers (This is usually a very long distance from the earth surface)

6. Length of a fork should be measured in centimeters (This is similar to the length of a pen).

7. Distance between cities should be measured in meters (except the distance is far apart, distance between close cities are measured in meters)

8. Width of the eyeball should be measured in millimeters (similar to the length of a stapler pin and fingernail).

Answer:

It took the projectile 120 s to reach the maximum height.

Explanation:

Given;

maximum height of the projectile, s = 180 km = 180,000 m

initial speed of the projectile, u = 3 km/s = 3000 m/s

final velocity at maximum height, v = 0

Apply the following kinematic equation for average velocity of the projectile;

[tex]s = (\frac{v+u}{2} )t\\\\(v+u)t = 2s\\\\t = \frac{2s}{v+u} \\\\t = \frac{2*180,000}{0+3,000}\\\\ t = 120 \ s[/tex]

Therefore, it took the projectile 120 s to reach the maximum height.

Answer:

The average acceleration of the object is 0.5 cm/s^2. Answer: A)

A) Correct. The average acceleration is 0.5 cm/s^2

B) Incorrect. The average acceleration is 0.5 cm/s^2

C) Incorrect. The average acceleration is 0.5 cm/s^2

D) Incorrect. The average acceleration is 0.5 cm/s^2

Answer:

A) 0.5 cm/s2

Explanation

I took the quiz the correct answer is A

The resistance in a circuit is directly proportional to the length of the wire. Thus as the length increases, R increases and current I decrease. But the voltage v remains constant.

Ohm's law states that, the voltage across a circuit is the product of the current and resistance.

Thus, V = I R

The resistance R is expressed by the expression:

R = ρ l/a

where ρ  is the proportionality constant called resistivity and l and a be the length and area of the wire.

Thus, as the length increases, resistance also increases.

The increase in resistance result in a decrease the current through  the circuit. Therefore, voltage remains constant. Hence, option B is correct.
