Answer:

Acceleration = 5.3645 m/s²

Explanation:

Given the following data;

Initial velocity, u = 0mph

Final velocity, v = 60 mph

Time, t = 5 seconds

To find the acceleration (also used in the second law of motion), we would use the following formula;

A = (v - u)/t

Conversion:

Miles per hour to meters per seconds;

0 mph = 0 mps

1 mph = 0.44704 mps

60 mph = 60 * 0.44704 = 26.8224 mps

Next, we find the acceleration;

Acceleration = (26.8224 - 0)/5

Acceleration = 26.8224/5

Acceleration = 5.3645 m/s²

Answer:

the average velocity of the ball is 5 m/s.

Explanation:

Given;

initial position of the ball, x₁ = 12 m East

final position of the ball, x₂ = 8 m West

initial time of motion, t₁ = 10.0 s

final time of motion, t₂ = 6.0 s

The average velocity is calculated as follows;

[tex]v = \frac{\Delta x}{\Delta t} = \frac{x_1 \ - \ x_2}{t_1 \ - \ t_2}[/tex]

let the Eastward direction be positive

Let the westward direction be negative

[tex]\frac{x_1 \ - \ x_2}{t_1 \ - \ t_2} = \frac{12 \ - \ (-8)}{10 -6}= \frac{20}{4} = 5 \ m/s[/tex]

Therefore, the average velocity of the ball is 5 m/s.

Answer:

n = 1.6

Explanation:

The formula for the calculation of the absolute index of refraction is given as follows:

[tex]n = \frac{c}{v}[/tex]

where,

n = index of refraction

c = speed of light in vacuum = 3 x 10⁸ m/s

v = speed of light in the piece of plastic = 1.87 x 10⁸ m/s

Therefore,

[tex]n = \frac{3\ x\ 10^8\ m/s}{1.87\ x\ 10^8\ m/s}[/tex]

n = 1.6

Answer:

[tex]\boxed {\boxed {\sf A. \ 36 \ m}}[/tex]

Explanation:

The distance an object travels is the product of its speed and time.

[tex]d=s \times t[/tex]

The object's speed is 12 meters per second and the time is 3 seconds.

Substitute the values into the formula.

[tex]d= 12 \ m/s \times 3 \ s[/tex]

Multiply. Note that the units of seconds will cancel, so we are left with meters as our units.

[tex]d= 12 \ m * 3[/tex]

[tex]d= 36 \ m[/tex]

The object travels a distance of 36 meters and choice A is correct.

This equation gives the magnitude of the electric field generated by a point charge Q. The distance r in the denominator is the separation between the point of interest and the point charge Q. Or the center of a spherical charge.

It is simple to determine the size of the electric field by calculating the force per charge on the test charge. From this definition, the common metric units for electric field strength are derived. Electric field units would be force units divided by charge units, as the definition of an electric field is a force per charge.

F = |qvBsin()| calculates the magnetic force's magnitude. The following factors are involved in determining the force's direction. A plane is first defined by the magnetic field vector, B, and the velocity vector, v. In or out of this plane, the magnetic force is perpendicular to it.

Therefore, The electric force F, or Coulomb force, exerted per unit positive electric charge q at that place can be used to determine an electric field's strength, or E = F/q.

Answer:

temporary iron r made up of soft iron its " true.."

Answer:

A

Explanation:

this because

gravitational potential energy = mass x height x gravitational field strength

so let's assume mass is 2 kg and gravitational field strength is 10 N /kg

so when height is very low, take it as 3 m

gravitational potential energy= 2 x 3 x 10 = 60 j

but when height is 6m

gravitational potential energy = 2 x 6 x 10 = 120 j

so when the height is the greatest, the gravitational potential energy is the highest

so A is the heighest so it has the highest gravitational potential energy.

This is the answer.

Answer:

0.0299 N

Explanation:

Applying,

F = Gmm'/r²................... Equation 1

Where F = gravitational force between the boulders, m = mass of the first boulder, m' = mass of the second boulder, r = distance between the boulders, G = Universal constant.

From the question,

Given: m = 7.5×10⁶ kg, m' = 9.2×10⁵ kg, r = 124 m

Constant: G = 6.67×10⁻¹¹ Nm²/kg²

Substitute these values into equation 1

F = (6.67×10⁻¹¹× 7.5×10⁶ × 9.2×10⁵ )/124²

F = (460.23)/15376

F = 0.0299 N

Answer:

0.3 N

Explanation:

Plug in all your variables:

6.67 ⋅ 10^-11 (7.5 ⋅ 10^6) (9.2 ⋅ 10^5)

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

                                 (124)^2

Once you plugin, You start to multiple solving to solve your problem:

Answer:

P = 5sin(880πt)

Explanation:

We write the pressure in the form P = Asin2πft where A = amplitude of pressure, f = frequency of vibration and t = time.

Now, striking the middle-A tuning fork with a force that produces a maximum pressure of 5 pascals implies A = 5 Pa.

Also, the frequency of vibration is 440 hertz. So, f = 440Hz

Thus, P = Asin2πft

P = 5sin2π(440)t

P = 5sin(880πt)

Explanation:

Newton's law of universal gravitation states that the force of gravity affects everything with mass in the universe. Newton's law also states that the strength of gravity between any two objects depends on the masses of the objects and the distance between them

Answer:

F' = 2F

Explanation:

The gravitational force of attraction between asteroids is given by Newton's Law of Gravitation:

[tex]F = \frac{Gm_1m_2}{r^2}[/tex]

where,

F = Force

G = Universal Gravitational Constant

m₁ = m₂ = m = mass of each asteroid

r = distance between asteroids

Therefore,

[tex]F = \frac{Gm^2}{r^2}[/tex]   --------------------- eq(1)

Now, if we double the mass of one asteroid:

[tex]F' = \frac{G(2m^2)}{r^2} \\\\F' = 2\frac{Gm^2}{r^2}[/tex]

using equation (1):

F' = 2F

Answer:

2 ZnS + 3O2 ---> 2ZnO + 2 SO2

Explanation:

2 ZnS + 2O2 ---> 2ZnO + SO2

There are 2 Zn atom on the LHS and 2 Zn on the RHS. Hence the Zn is balanced on both sides of the equation.

There are two S atom on the LHS but there is only one S atom on the RHS.

Hence we will balance the S atoms

2 ZnS + 2O2 ---> 2ZnO + 2 SO2

Now the oxygen is unbalanced as there are three oxygen molecule on the RHS but only two on the LHS.

Hence, the balanced equation would be

2 ZnS + 3O2 ---> 2ZnO + 2 SO2

Answer:

C. a disturbance that travels through a medium with a transfer of energy and without a transfer of matter

Explanation:

A wave is any disturbance that transfers energy from one location to the other via a substance called medium. It is important to note that a wave only conveys energy and not matter. For example, sound wave is a type of wave that carries sound energy from one place to another via mediums such as water, air etc.

Hence, according to this question, a wave can be described as a disturbance that travels through a medium with a transfer of energy and WITHOUT A TRANSFER OF MATTER.

Answer:

See Explanation

Explanation:

According to Newton's second law of motion, the acceleration of a body is proportional to the net external force that acts on the body.

A body accelerated when it is acted upon by an unbalanced net external force.

When the external forces acting on a body are balanced, the effect of each force is cancelled by the other hence the body is not accelerated according to Newton's second law.
