Answer:

I think it is O only nonliving

Answer:

changing the direction in which a force is exerted

Answer:

When you stretch or compress a spring you work against the restoring force of the spring. This work is stored as elastic potential energy in the spring. The more you stretch or compress the spring, the more work is done by you and more energy is stored.

This is also evident from the expression of the potential energy ( U ) -

U=(1/2)kx2

Where x is the displacement from the unstretched position of the spring. Greater is the x. more is the energy stored.

Answer:

Explanation:

Given parameters:

Electrical energy  = 18J

Quantity of charge Q = 12C

Unknown:

Voltage  = ?

Solution:

The expression of electrical potential energy is given as:

      Electrical potential energy  = [tex]\frac{1}{2}[/tex] c v²

c is the quantity of charge

v is the voltage

           18  =  [tex]\frac{1}{2}[/tex]  x 12 x v²  

           18 = 6v²  

              v² = 3  

               v = 1.7v

[tex]\frac{1}{2}[/tex]Answer:

    [tex]v_{exit } < v_{enter}[/tex]

Explanation:

To propose the solution of this problem we must use the relationship between work and energy

         W = ΔK

the change in kinetic energy is

         ΔK = K_f -K₀

         ΔK = ½ m v_f² - ½ m v₀² = ½ m (v_f² - v₀²)

in this case

         ΔK =  [tex]\frac{1}{2} m ( v_{exit}^2 - v_{enter}^2 )[/tex]

we can find work with the first law of thermodynamics

         [tex]\Delta E_{int}[/tex] = Q + W

where \Delta E_{int} is the internal energy of the body, usually measured in the form of an increase in the temperature of the system

          W = \Delta E_{int} - Q

if we consider that the internal energy does not change

         W = -Q

we substitute everything in the first equation

        -Q =   [tex]\frac{1}{2} m ( v_{exit}^2 - v_{enter}^2 )[/tex]

Because they are squared, the variables are positive, therefore, for the equation to be fulfilled, the exit velocity must be less than the entrance velocity.

            [tex]v_{exit } < v_{enter}[/tex]

Answer:

(a) The range of the projectile is 31,813.18 m

(b) The maximum height of the projectile is 4,591.84 m

(c) The speed with which the projectile hits the ground is 670.82 m/s.

Explanation:

Given;

initial speed of the projectile, u = 600 m/s

angle of projection, θ = 30⁰

acceleration due to gravity, g = 9.8 m/s²

(a) The range of the projectile in meters;

[tex]R = \frac{u^2sin \ 2\theta}{g} \\\\R = \frac{600^2 sin(2\times 30^0)}{9.8} \\\\R = \frac{600^2 sin (60^0)}{9.8} \\\\R = 31,813.18 \ m[/tex]

(b) The maximum height of the projectile in meters;

[tex]H = \frac{u^2 sin^2\theta}{2g} \\\\H = \frac{600^2 (sin \ 30)^2}{2\times 9.8} \\\\H = \frac{600^2 (0.5)^2}{19.6} \\\\H = 4,591.84 \ m[/tex]

(c) The speed with which the projectile hits the ground is;

[tex]v^2 = u^2 + 2gh\\\\v^2 = 600^2 + (2 \times 9.8)(4,591.84)\\\\v^2 = 360,000 + 90,000.064\\\\v = \sqrt{450,000.064} \\\\v = 670.82 \ m/s[/tex]

\frac{\lambda }{2} is the minimum interplanar spacing which is required for Bragg's diffraction to occur.

Answer:Light is made up of wavelengths of light, and each wavelength is a particular colour. The colour we see is a result of which wavelengths are reflected back to our eyes. The visible spectrum showing the wavelengths of each of the component colours. The spectrum ranges from dark red at 700 nm to violet at 400 nm.  

Explanation:

hope it helps

Answer:When light hits an object, the object reflects some of that light and absorbs the rest of it. Some objects reflect more of a certain wavelength of light than others. That's why you see a certain colour. For example, a lemon reflects mainly yellow light.

Explanation:

The coordinate sketch for the system is shown in the attached file below. Also, in the cartesian coordinate system, since the height is less than the length and width, we did neglect the height. Thus, we eliminate the height and converted it to a two-dimension.

Answer:

A.The tortoise is moving at a constant speed

Explanation:

The chart shows the tortoise covering a distance of 0.5 meters every 60.0 seconds. Since this rate of motion is not changing, the tortoise is moving at a constant speed.

The diagram shows the tortoise moving at a constant speed. Thus the correct option is option A.

Speed is defined as how far the object travels. It is also defined as the rate of change of distance per unit of time. Speed is the scalar quantity and the unit of speed is m/s.

Speed is denoted by the letter v. v = s/t, where s is the distance traveled along the path and t is the time taken by the object to move along the path.   The SI unit of distance is meter and the unit of time is seconds.

When the object covers an equal distance at equal intervals of time is called uniform speed. When the object covers unequal distance with equal intervals of time or equal distance with unequal intervals of time is called Non-uniform speed.

The graph shows the Tortoise covers 0.5 m in 60 seconds is called uniform speed. Thus, option A is correct.

earth has gravity force that is high than the moon gravity force which is 1/6 of earth gravity

Earth has gravity force that is high than the moon gravity force which is 1/6 of earth gravity.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

The force on the moon is less than earth as gravity is 1/6 on the moon

When man jump than he will jump high on the moon than the earth.

Earth has gravity force that is high than the moon gravity force which is 1/6 of earth gravity.

Answer:

441 N

Explanation:

weight = mass x gravity

w = m x g.

We know that gravity = 9.8 m/s^2 and mass = 45 kg.

w = 45 kg x 9.8 m/s^2

w = 441 N

So the weight of the object is 441 N (newtons).

Answer:441 N.

Explanation:

The weight of 45 kg at rest on the surface of the Earth is about 45 * 9.8 N = 441 N.

Answer:

1.0 volts

Explanation:

Given that:

The potential difference between the plate V = 10 V

C = 0.160 pF = 0.160 × 10⁻¹² F

The charge on the capacitor

Q = CV

Q = 0.160 × 10⁻¹² × 10

Q = 1.6 × 10⁻¹² C

It implies that the positive plate of capacitor has +1.6 × 10⁻¹² C charge while the negative plate has -1.6 × 10⁻¹² C

The number of excess electrons on the negative plate is:

[tex]n = \dfrac{q}{e}[/tex]

[tex]n = \dfrac{-1.6\times 10^{-12}}{-1.6\times 10^{-19}}[/tex]

[tex]n = 1.0 \times 10^7[/tex]

Thus, electron deficiency on the positive plate is [tex]1.0 \times 10^7[/tex]

The net negative charge that moves towards the positive plate is :

q = number of electrons moved × e

[tex]q = 1\times 10^6 \times (-1.6 \times 10^{-19})[/tex]

[tex]q = -1.6 \times 10^{-13} \ C[/tex]

Now, the net charge on the positive plate is:

[tex]q_{net} = q +q' \\ \\ q_{net} = (1.6 \times 10^{-12}) + (-1.6 \times 10^{-13})[/tex]

[tex]q_{net} =1.44 \times 10^{-12} \ C[/tex]

The potential difference between the plate;

[tex]V_{new} = \dfrac{q_{net} }{c}[/tex]

[tex]V_{new} = \dfrac{1.44 \times 10^{-12} }{0.16 \times 10^{-12}}[/tex]

[tex]V_{new} = 9.0 V[/tex]

The reduction in potential difference

[tex]\Delta V = V - V_{new}[/tex]

[tex]\Delta V = 10 - 9.0[/tex]

[tex]\mathbf{\Delta V = 1.0 \ volts}[/tex]

Answer:

the average speed of the car is 170 mph.

Explanation:

Given;

initial speed, u = 70 mph

time of motion, t₁ = 3 hours

final speed, v = 20 mph

time of motion, t₂ = 2 hours

The average speed of the car is calculated as;

[tex]v' = \frac{70(3) - 20(2)}{3-2} \\\\v' = 170 \ mph[/tex]

Therefore, the average speed of the car is 170 mph.
