in figure Car’s weight = 16,000 N. What is the external input force?

Answer:

m= 0. 113 kg

W = 1.1074 N

g = 9.8 m/ s²

m= 870 kg

W = 8526 N

g = 9.8 m/s²

a) weight on earth:

weight = mass × acceleration due to gravity (g)

g on earth = 9.8 m/s²

W = 75 × 9.8

W = 735 N

b) g on Mars

285 = 75 × g

g = 285/ 75

g = 3.8 m/ s²

Answer: the electromagnetic spectrum

Explanation:

The full range of frequencies of electromagnetic radiation is called the electromagnetic spectrum. From longest to shortest wavelengths, it includes radio waves, microwaves, infrared light, visible light, ultraviolet light, X rays, and gamma rays.

Explanation:

amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position

Answer:

1 m/s

Explanation:

Use SUVAT and the equations of motion:

S

U = 0 km/s since it started at rest.

V = 2 km/s

A

T = 5.8 seconds

Equation used: [tex]v=\frac{v+u}{2}[/tex]

[tex]v=\frac{2+0}{2}[/tex]

v=1

Since the force is perpendicular to the displacement of the ball, the total work done by the force is 50 Nm.

Given the following data:

To find the total work done by the force:

The work done by an object is the product of the perpendicular force acting on the object and the distance it covers.

Mathematically, work done is given by the formula:

[tex]Work\;done = Force[/tex] × [tex]distance[/tex]

Substituting the given parameters into the formula, we have;

[tex]Work\;done = 10[/tex] × [tex]5[/tex]

Work done = 50 Nm.

Avg speed

[tex] \frac{dp}{dt } = \frac{5 - 4}{12 - 0} = \frac{1}{12} m \: per \: s[/tex]

avg velocity

[tex] \frac{5}{4} m \: per \: s[/tex]

Hi there!

Average speed = Distance / time

From the previous question, distance = 17m, so:

Speed = 17/12 ≈ 1.417 m/s

Average velocity = DISPLACEMENT/ time

Displacement = 1m, so:

Average velocity = 1/12 ≈ 0.083 m/s

Answer:

1.647376

Explanation:

Change the divisor 12.96 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations:

2135 ÷ 1296 = 1.647376

and therefore:

21.35 ÷ 12.96 = 1.647376

Both calculated to 6 decimal places.

f=3750N

Answer:

W= work

F= force

D= Displacement

Explanation:

Work can be calculated with the equation: Work = Force × Distance.

Answer:

300km

Explanation:

we use the formula s=d/t and solve for d.

d=st

s1=70km/h

s2=80km/h

t=2h

total d= (ts1)+(ts2)

=2(70)+2(80)

=300km

Image result for Which describes refraction? the reflection of light as it passes through a substance the focusing of light as it passes through a substance the emission of light as it passes through a substance the bending of light as it passes through a substance

When electromagnetic radiation, in the form of visible light, travels from one substance or medium into another, the light waves may undergo a phenomenon known as refraction, which is manifested by a bending or change in direction of the light.

Explanation:

magnitude=force/charge

=(2.6N)/(1.5 ×10^-6)

=1.7 × 10^6 N/C

Energy is what makes change happen and can be transferred form one object to another. Energy can also be transformed from one form to another. Power is the rate at which energy is transferred. It is not energy but is often confused with energy.

Energy and power are closely related but are not the same physical quantity. Energy is the ability to cause change; power is the rate energy is moved, or used.

Known as the “plica semilunaris,” it's much more prominent in birds and a few mammals, and functions like a windshield wiper to keep dust and debris out of their eyes. But in humans, it doesn't work. It's vestigial, meaning it no longer serves its original purpose.

because the regions near the equator are called tropical regions

Answer:

For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

Answer:4.99km

Explanation:

We'll use s for distance, and t for time in seconds.

s = (1/2)at²

t = 0.5 minute*(60sec/1min)=30 sec

s = (1/2)*(2.2m/s²)(30sec)²

s = 990m

Reference point is 4km at start.  Distance from reference point is 9km + 0.990km = 4.99km

Answer:

48 / 3 = 16

1 / 16 of the original amount is to remain

4 half lives = 1/2 * 1/2 * 1/2 * 1/2 = 1/16

After 4 half lives 1/16 of the original amount is present

4 half-lives * 3.8 days / half-life = 15.2 days

After 15.2 days only 3 g will be present
