Answer:

Inverse

Explanation:

The force of gravity between two objects follows an inverse square law with regard to the distance between them.

The inverse square law refers to any law that stipulates that a particular quantity varies inversely to the square of the distance to its source and according to the law of universal gravitation, the gravitational force of attraction between two objects is inversely proportional to the square of the distance separating the two objects.

Hence, the law of universal gravitation obeys the inverse square law.

Answer:

0.31s

Explanation:

Given parameters:

Frequency of the ocean waves  = 3.2Hz

Unknown:

Period of the waves  = ?

Solution:

The period of a wave is the inverse of the frequency of a wave;

       Period  = [tex]\frac{1}{Frequency}[/tex]

Now insert the parameters and solve;

       Period  = [tex]\frac{1}{3.2}[/tex]   = 0.31s

The period of the wave is 0.31 s.

The question above can be solved using the relationship between period and frequency (T = 1/F).

Frequency: This can be defined as the number of complete oscillations performed by a wave in one second.

Period: This is the time required by a wave to complete one oscillation.

The relationship between period and frequency

Formula:

T = 1/F....................... Equation 1

From the question,

Given:

Substitute this value into equation 1

Hence, the period of the wave is 0.31 s.

Answer:

Explanation:

The question is incomplete, the complete question is;

A car is moving  at a constant speed of 3 m/s when a force of 25N is acting on it. What will happen if the force is changed to 35N?

The car will move at a constant speed of 13 m/s

The speed of the car will not change.

The speed of the car will increase.

The speed of the car will decrease to 1 m/s

Answer:

The speed of the car will increase.

Explanation:

When a the force acting on an object moving at constant velocity is changed, its velocity changes accordingly.

The question said that the car was moving at a constant velocity of 3m/s when a 25 N force is applied, then the car must move faster than 3 m/s when a 35 N force is applied since the 35N force is greater than the 25 N force.

Hence the answer above.

Answer:

The potential energy (P.E) at the top is 392 J

The kinetic energy (K.E) at the top is 0 J

The potential energy (P.E) at the halfway point is 196 J.

The kinetic energy (K.E) at the halfway point is 196 J.

Explanation:

Given;

mass of the rock, m = 2 kg

height of the cliff, h = 20 m

speed of the rock at the halfway point, v = 14 m/s

The potential energy (P.E) and kinetic energy (K.E) when its at the top;

P.E = mgh

P.E = (2)(9.8)(20)

P.E= 392 J

K.E = ¹/₂mv²

where;

v is velocity of the rock at the top of the cliff = 0

K.E = ¹/₂(2)(0)²

K.E = 0

The potential energy (P.E) and kinetic energy (K.E) at the halfway point;

P.E = mg(¹/₂h)

P.E = (2)(9.8)(¹/₂ x 20)

P.E = 196 J

K.E = ¹/₂mv²

where;

v is velocity of the rock at the halfway point = 14 m/s

K.E = ¹/₂(2)(14)²

K.E = 196 J.

The potential energy (P.E) at the top is 392 J

The kinetic energy (K.E) at the top is 0 J

The potential energy (P.E) at the halfway point is 196 J.

The kinetic energy (K.E) at the halfway point is 196 J.

Since

mass of the rock, m = 2 kg

height of the cliff, h = 20 m

speed of the rock at the halfway point, v = 14 m/s

We know that

P.E = mgh

P.E = (2)(9.8)(20)

P.E= 392 J

Now

K.E = ¹/₂mv²

here.

v is velocity of the rock = 0

K.E = ¹/₂(2)(0)²

K.E = 0

Now

The potential energy (P.E) and kinetic energy (K.E) at the halfway point;

P.E = mg(¹/₂h)

P.E = (2)(9.8)(¹/₂ x 20)

P.E = 196 J

K.E = ¹/₂mv²

Here,

v is the velocity of the rock= 14 m/s

K.E = ¹/₂(2)(14)²

K.E = 196 J.

Answer:

a. I =  -3mv₀/2 b. F = -3mv₀/2t

Explanation:

a. Use the impulse-momentum to write an equation for the  system which is the cart only.

We know Impulse , I = Δp where Δp = change in momentum.

Now, Δp = m(v - u) where m = mass of cart, u = initial velocity of cart = v₀ and v = rebound velocity of cart = -v₀/2 (negative since it moves in the opposite direction to u)

So, I =  Δp = m(v - u)

Substituting the values of the variables into the equation, we have

I = m(-v₀/2 - v₀) = -3mv₀/2

So, I =  -3mv₀/2

b. If the time during which the bumper exerts a force on the cart is t, write an expression for the force F exerted on the cart in terms of the given variables.

We know impulse I = Ft where F = force exerted on the cart and t = time force acts

Also, I = -3mv₀/2

So, Ft = -3mv₀/2

F = -3mv₀/2t

The key idea behind the synthesis, processing and application of alloys consist in combining desire qualities from each mineral component in the form of a material.

Explanation:

The key idea behind the synthesis, processing and application of alloys consist in combining desire qualities from each mineral component in the form of a material. For example, steel is the combination of iron, which is ductile but prone to rusting in wet environments, and carbon, which offers high hardness and additional resistence to rusting in wet environments, but is fragile. Hence, steel is more resistant to rusting, ductile as iron and more resistant than iron.

Answer:

F

Explanation:

The average velocity is the ratio of total displacement and time.The average speed is the ratio of total distance and time.Therefore the average speed and average velocity are equal if the total displacement is equal to the total distance that is if the body travels along a straight line without changing the direction.

Momentum

Momentum is often defined as "mass in motion".

Since all objects have mass, if it's moving, then it has momentum. The momentum is a vector and It can be calculated as the product of the mass by the velocity of the object:

[tex]\vec p = m\vec v[/tex]

If only magnitudes are considered:

p = mv

We are given that an m=9.5 kg turkey is running at v=4 m/s. Below is the formatted data:

p = ?

m = 9.5 kg

v = 4 m/s

Formula

p = m v

[tex]p = 9.5 \cdot 4[/tex]

p = 38 kg.m/s

The element that unicornium-210 (210Ui) could not decay into based on atomic mass alone is 90Sr.

A radioactive isotope is a type of atom that has an unstable nucleus that spontaneously decays or disintegrates, emitting radiation in the form of particles or electromagnetic waves. This process is known as radioactive decay.

The unstable nature of the nucleus arises from having too many or too few neutrons compared to the number of protons in the atom, which affects the stability of the atomic nucleus. The decay of radioactive isotopes can have practical applications in fields such as nuclear medicine, energy production, and environmental monitoring, but can also pose health and safety risks if not handled properly.

Answer:

Spherical concave mirrors

Explanation:

Like spherical convex mirrors, spherical concave mirrors have a focus. If the object is closer to the mirror than the focal point is, the image will be virtual, like we talked about before for the plane mirror and the convex mirror.

Concave mirrors, on the other hand, can have real images. If the object is further away from the mirror than the focal point, the image will be upside-down and real---meaning that the image appears on the same side of the mirror as the object.

The closer the object comes to the focal point (without passing it), the bigger the image will be.

You can try this yourself by looking into the concave side of a shiny spoon. If you look into the spoon while holding it at arm’s length, you’ll see an extremely magnified, upside-down image of your face. But as you bring the spoon closer to your eyes, the image will get bigger and bigger.
