Answer 2

A battery supplies electrical energy to a circuit Chemical reactions in a battery cause positively and negatively charged particles to separate and become concentrated at the battery terminals. The correct option is A.

What is a chemical reaction?

A chemical reaction is a process in which one or more substances, also known as reactants are converted to one or more different substances, known as products. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products

Chemical reactions in a battery cause positively and negatively charged particles to separate and become concentrated at the battery terminals resulting in the transformation into electrical energy therefore the correct option is A.

1. What is the gravitational force of attraction between two 800 kg spherical objects that are 5 m apart? What would the gravitational force of attraction between these two objects be if the distance between them was changed to 10 m?

Answers

Answer:

the force of gravity between them is quadrupled .

Explanation:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.

A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the ball is

Answers

Answer:

0 m/s

Explanation:

In this problem,

A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. We need to find the speed of the ball at the maximum height. When an object reaches its maximum height, after then it starts to decrease its speed. As a result, the speed of the ball will be equal to 0 m/s.

The speed of the ball thrown upwards is zero when the object reaches maximum height.

The given parameter:

maximum height, h = 30 m

The velocity of an object thrown upwards decreases with time because the object is moving against gravity, and the eventually becomes zero when the object reaches maximum height.

[tex]v_f = v_0 - gt= 0[/tex]

Thus, the speed of the ball thrown upwards is zero when the object reaches maximum height.

where is the centripetal force directed on a banked curve?

Answers

Answer:

The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve.

Explanation:LET ME KNOW IF ITS WRONG. HAVE A NICE DAY!!!!!!!!!!

Answer: The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve. The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path. In order for a car to move around a circular track, something must provide a centipetal force. One source of the centripetal force is friction between the tires and the road. This means that the tires do not need to supply any friction at all to keep the car from slipping sideways. ...

A wave vibrates up and down 22 cycles in 7 seconds with a wave speed of 57. Calculate the
wavelength. (Round to the 2nd number after the decimal)

Answers

Answer:

18.14m

Explanation:

Given parameters:

Frequency = [tex]\frac{22}{7}[/tex]cycles/s

Speed of wave = 57m/s

Unknown:

Wavelength  = ?

Solution:

The speed of a wave is related to frequency and wavelength using the expression below;

         V = f x λ

V is the speed of the wave

f is the frequency

λ is the wavelength

  Insert the parameters and find λ;

        57  =  [tex]\frac{22}{7}[/tex] x λ

       λ = 57 x [tex]\frac{7}{22}[/tex]   = 18.14m

An object travels in a straight line for 1200 m at a velocity of 50 m/s, what is its time of travel?​

Answers

Given that,

distance = d = 1200m

velocity/speed = s = 50m/s

time = t

Also,

s = d/t

And,

t = d/s

t = 1200/50

t = 120/5

t = 24

Therefore, it takes 24s to travel.

Answer: Therefore, the travel time of a car that travels 1200 meters at 50 m/s is 24 seconds.

Explanation:

An object travels in a straight line for 1200 m at a velocity of 50 m/s, what is its time of travel?​

Data:

d = 1200 m

V = 50 m/s

t = ?

The formula for uniform motion is:

V = d/t

Where

V = speedd = distancet = time

We clear the formula for time t:

t = d/v

t = (1200 m)/(50 m/s)

t = 24 s

Therefore, the travel time of a car that travels 1200 meters at 50 m/s is 24 seconds.

A horse accelerates from rest for 1 s and covers a distance D. If instead the accelerates from rest with the same accelerations for 2 s will the distance it covers be equal to 2D, 4D, or 9D

Answers

Answer:

4D

Explanation:

We will use 2nd equation of motion in this question:

s = Vi t + (0.5)gt²

where,

s = distance covered

t = time taken

g = acceleration due to gravity

For t = 1 s:

s = D

Therefore,

D = (0 m/s)(1 s) + (0.5)g(1 s)²

D = 0.5g   -------------- equation (1)

For t = 2 s:

s = D

Therefore,

s = (0 m/s)(1 s) + (0.5)g(2 s)²

s = 0.5g(4)

using equation (1):

s = 4D

therefore, correct answer is:

4D

The car's initial speed was 15 m / s and the distance the car travels before it comes to a complete stop after the driver applies the brakes is 63m. What is the magnitude of the car's acceleration?

Answers

Initial speed of the car (u) = 15 m/s

Final speed of the car (v) = 0 m/s (Car comes to a complete stop after driver applies the brake)

Distance travelled by the car before it comes to halt (s) = 63 m

By using equation of motion, we get:

[tex] \bf \longrightarrow {v}^{2} = {u}^{2} + 2as \\ \\ \rm \longrightarrow {0}^{2} = {15}^{2} + 2 \times a \times 63 \\ \\ \rm \longrightarrow 0 = 225 + 126a \\ \\ \rm \longrightarrow 126a = - 225 \\ \\ \rm \longrightarrow a = - \dfrac{225}{126} \\ \\ \rm \longrightarrow a = - 1.78 \: m {s}^{ - 2} [/tex]

[tex] \therefore [/tex] Acceleration of the car (a) = -1.78 m/s²

Magnitude of the car's acceleration (|a|) = 1.78 m/s²

A truck moving due south takes a turn and starts moving towards east while maintaining the same speed.
Its velocity remains constant.
It covers unequal distances in equal intervals of time.
Its velocity changes
None of the above

Answers

Answer:

Its velocity changes

Explanation:

When the truck changes direction, its velocity changes.

Velocity is a vector quantity that specifies the magnitude of motion and direction it is taking.

When direction changes, the velocity of a body will also change. This is unlike speed which is a scalar quantity.

 Velocity is the displacement divided by time taken.

in the circular path. (3 points)
a) 24 N toward the center of the circle
b) 24 N along the line tangent to the circle
c) 1.587 E3 N along the line tangent to the circle
d) 1.587 E3 N toward the center of the circle

Answers

Answer: D) 1.587 E3 N toward the center of the circle

This is the same as saying 1.587*10^3 newtons, or we can say 1587 newtons

=================================================

Work Shown:

m = mass = 660 kilograms

v = velocity = 11.5 meters per second

r = radius of circle = 55.0 meters

-------------

F = centripetal force = inward pulling force toward center of circle

F = (m*v^2)/r

F = (660*11.5^2)/55

F = 1587

F = 1.587 * 10^3

F = 1.587 E 3

The "E 3" notation is what many calculators display scientific notation to be

The units for the force here are in newtons.

The force is pulling on the object toward the center of the circle, which helps keep the car on the circular path, rather than it going off on a tangent.
