m is the mass

v is the speed

 Now insert the parameters and solve;

     K.E  =  [tex]\frac{1}{2}[/tex]  x 20 x 10²   = 1000J

Answer:12

Explanation:

Answer:

Yes

Explanation:

It is possible because a stone on the ground is at rest with respect to earth but at the same time earth is moving around the sun. That means everything on earth is moving so with respect to sun the stone is also moving. That is how the stone is in rest also and is in motion also.

Formula for kinetic energy:

K = ½mv²

Given:

v = 1.4 m/s

m = 71 kg

K = ½ · 71.0 kg · (1.4 m/s)²

K = 35.5 kg · 1.96 m²/s²

K = 69.58 J

Answer:

20N

Explanation:

Given parameters:

Mass of the block  = 4kg

Acceleration  = 5m/s²

The speed of the block after the student pushes it is 10m/s.

Given the data in the question;

Since the block is initially at rest,

Final velocity; [tex]v =\ ?[/tex]

To determine the final velocity; we use the First Equation of Motion:[tex]v = u + at[/tex]

Where v is final velocity, u is initial velocity, a is acceleration and t is time taken.

We substitute our values into the equation

[tex]v = 0 + [ 2m/s^2\ *\ 5s]\\\\v = 2m/s^2\ *\ 5s\\\\v = 10\frac{ms}{s^2}\\\\v = 10m/s[/tex]

Therefore, the speed of the block after the student pushes it is 10m/s.

Answer:

Energy

Explanation:

One ways of stating the law of conservation of energy is that "you cannot get more energy from a machine than the amount of energy you put into it".

The law of conservation of energy states that in a system, energy is neither created nor destroyed but transformed from one form to another.

The energy in a system does not increase based on the premise of this law.

Explanation:

Here,

Mass=16,500kg.

speed=14 m/s.

we know that,

[tex]\tt{ p=m×v }[/tex] ⠀

where,

p=momentum

m=mass

v=velocity

according to the question,

[tex]\tt{ momentum =mass×velocity }[/tex] ⠀

[tex]\tt{ 16500×14 }[/tex] ⠀

[tex]\tt{ 231000~kg.m/s }[/tex] ⠀

Answer:

This is true

Explanation:

This is true because in other To measure the potential difference that is across a circuit, we have to place the device called the voltmeter to be in parallel withe the circuit, so as to get a measurement of the difference in energy from one side of the circuit to the other side. We can also refer to the Potential difference as the voltage and it is measured in volts using a voltmeter

Answer:

5 km

0

Explanation:

The question says the truck travelled to and fro from the stone quarry.

When going to the stone quarry, the distance was 2.5 km to the east.

On returning, the distance back is also 2.5km

Therefore total distance travelled is 2.5km + 2.5km

= 5km

The displacement 8s dependent on what is the initial and also the final position. The initial and the final position are one and the same thing. Because the truck starts and goes back to the same position, the displacement is zero.

Answer:

A bicycle on the top of the hill has the highest potential energy, and when the bike goes down, it transfers to kinetic because it is moving

yeah

Answer:

D. 0.60 um

Explanation:

Given the following data;

Frequency = 5.0x10^14 Hz

Speed = 3 x 10^8 m/s

To find the wavelength;

Wavelength = speed/frequency

Substituting into the equation, we have

Wavelength = 3 x 10^8/5.0x10^14

Wavelength = 6 × 10^7m

But 1 meter (m) = 1000000 micrometer (um)

6 × 10^7 meter = 0.6 micrometer.

Distance d=280

Generally the Newtons equation for motion is mathematically given as

Acceleration

[tex]v^2=2as[/tex]

[tex]a=\frac{V^2}{2s}[/tex]

[tex]a=\frac{28^2}{2*280}[/tex]

Answer:

Educational institutions can influence what psychological perspectives are taught, studied, and researched. Take, for example, behaviorism. Before the cognitive perspective re-emerged, behaviorism was the dominant perspective being taught in most universities. Personal ideology can also affect which perspective a psychologist supports, the course of research a psychologist undertakes, and also a psychologist's perception and interpretation of research findings. For example, during the dominance of behaviorism, psychologists were discouraged from studying cognitive processes. As a result, much of the research conducted had a behaviorist slant to it.
