isaac newton discovered that the color white is created when light passes through a prism. t or f?

Answer:

D. 3.6m/s

Explanation:

The equation for wave speed can be used to calculate the speed of a wave when both wavelength and wave frequency are known. Consider an ocean wave with a wavelength of 1.2 meters and a frequency of 3 hertz. The speed of the wave is: Speed = 1.2m x 3wave/s = 3.6 m/s

Answer: c

Explanation:

Answer:

See Below

Explanation:

It is a change in the distribution of electric charge on one object because of  the influence a nearby object that has an electric charge.  So if an object with a negative charge is brought near to a neutral object, the neutral object will alter itself so that one side becomes more positive and the other side becomes more negative.

Electrostatic induction occurs whenever any object is placed in an electric field.

Answer:

250N

Explanation:

Coefficient of friction=frictional force/Normal force

0.5= Fr/500N

Fr= 250N

Answer:

Final velocity = 7.4m/s

Explanation:

Use the equation:

acceleration = (final velocity - initial velocity)/time

Rearrange to get:

final velocity = (acceleration * time) + initial velocity

Now just substitute with the values you already have:

Final velocity = (-9.8m/s^2 * 0.7s) + 0.5m/s

Final velocity = 7.36m/s

We are using 2 sig-figs, so:

Final Velocity = 7.4m/s

Answer:

Your displacement would be

s = 22.5 m

s=1/2(v+u)t

Answer:

20m/s = 72,000m, 3m/s = 10800m

Explanation:

5 star please

Answer:

a bicycle has more kinetic energy cuz kinetic energy depends on mass and velocity.bicycle has more mass than a tennis ball.

From the information provided, the velocity after 2 seconds is  11 m/s.

From the equations of motion;

v = u + at

Where;

v = final velocity

a = acceleration

t = time taken

The initial velocity of the bike was 7 m/s and its acceleration is  2 m/s2. This change occurred within a time of 2 seconds.

Hence;

v = 7 + 2(2)

v = 11 m/s

The velocity after 2 seconds is  11 m/s.

Explanation:

Because there is a redius do this question is talking about the acceleration force which= mv^2/r

so a=15^2/80=2.8125 m^2/s

so the force will be = m.a

F =1700×2.8125=4781.25 N

The gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object

The gravitational potential energy of a falling apple is maximum when the apple is at maximum height. As the apple begins fall to the ground the potential energy decreases and it will be transformed to kinetic energy.

[tex]P.E_i + K.E_i = P.E_f + K.E_f[/tex]

The potential difference in a battery is total energy stored in the battery.

Thus, the gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object.

The similarity is that both the battery and the falling apple have stored energy.

We define the potential energy of an object as stored energy in that object.

A battery has potential energy, it is stored until you connect it to something and allow that energy to flow.

Similarly, when the apple is in the air it has potential energy, that will be transformed into kinetic energy as it falls (as the apple falls, its velocity increases, thus, the kinetic energy increases).

So both, the apple and the battery have stored energy, and that is the similarity between these two.

Answer:

Es una constante porque sigue funcionando y debido a la gravedad, tú tendrías que ser tú quien la detenga si está bajando en lugar de hacia arriba.

Explanation:

1. Weight is the gravitational pull with which the earth attracts the body towards the center of the earth. The S.I unit is Newton (N)

2. The weight of an object is related to its mass with the below equation.

W = mg

Where W = weight, m = mass and g = acceleration due to gravity

3. The mass m = 50 kg and g = 9.8 m/[tex]s^{2}[/tex]

Substitute the parameters in the equation above.

W = 50 x 9.8

W = 490 N

4. An object is accelerating when it speeds up. If the object slows down, it means it is decelerating. The correct answer is option A

5. Newton's second law of motion is:

F = ma

Where F = force applied, m = mass and a = acceleration

Therefore, Newton's second law of motion relates an object's acceleration to its net force acting on it. The correct answer is option C

6. According to Newton's second law of motion which relates an object's acceleration to its mass, doubling the net force acting on an object a doubles its acceleration. Because mass is always constant.

7. Since the weight of an object is related to its mass with the equation.

W = mg,  If the mass of an object doubles, its weight will also doubles. Option A is the correct answer.

8. If you know the mass of an object, you can calculate its weight with the formula F = mX when X = 9.8m/[tex]s^{2}[/tex]

9. Force is expressed in unit as Newton (N)

10. The parameters given are :

mass m = 20kg

Force F = 40N

To calculate acceleration, use the formula F = ma

Substitute all the parameters into the equation.

40 = 20a

a = 40/20

a = 2m/[tex]s^{2}[/tex]

The correct option is D

Find the distance traveled by a car that travels with an average speed of 110 km/h for 3.5 h

To solve for distance:

d = v t

d = 110 × 3.5

d = 385 km

How long does it take a baseball moving with an average speed of 35 m/s to travel 18 m?

To solve for time:

t = d/v

t = 18 / 35

t = 0.514286

t = 0.5 s

What is the average speed of a car that travels 870 km in 14.5 h?

To solve for average speed:

v = d/t

v = 870 / 14.5

v = 60 km/h

Answer is 4 m/s

Let :-

Constant velocity = v

Time (t) = 2 seconds

Height (h) = 16 metres

As the raindrop has constant velocity, we can write that :

[tex] \frac{h}{2} = vt[/tex]

Substituting the values, we get,

[tex] \frac{16}{2} = v \times 2[/tex]

[tex]8 = v \times 2[/tex]

[tex] \frac{8}{2} = v[/tex]

[tex]v = 4 \: m/s[/tex]

Therefore, the velocity of the raindrop is 4 m/s.
