acceleration due to gravity
on its current planet?
Please help

Answers

Answer:

5.59 m/s2

Explanation:

F = 1900 N

m = 340 kg

F = ma

Therefore, a = 1900/340 = 5.59

The energy of a photon was found to be 3.38 x 10-19 J. Planck's constant is 6.63 x 10-34 J. S. Which color of light corresponds to this photon?
violet
green
yellow
red

Answers

Answer:

The correct option is (c).

Explanation:

Given that,

The energy of a photon is, [tex]E=3.38\times 10^{-19}\ J[/tex]

We need to tell the color of this light. We know that, the energy of a photon is given by :

[tex]E=\dfrac{hc}{\lambda}[/tex]

Where

c is the speed of light

[tex]\lambda=\dfrac{hc}{E}\\\\\lambda=\dfrac{6.63\times 10^{-34}\times 3\times 10^8}{3.38 \times 10^{-19}}\\\\\lambda=5.88\times 10^{-7}\ m\\\\\lambda=588\ nm[/tex]

The wavelength of yellow light is approx 580 nm. Hence, we can say that this photon corresponds to yellow light.

Explain the law of inertia in your own words.

Answers

An object at rest will remain at rest unless acted on by a force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by a force.

Explanation:

Answer:

Law of inertia is Newton's first law of motion..

Explanation:

It means that a body will tend to be in it's motion or tend to move in a straight line unless any external force is acted upon it..

Eg: while you are travelling in bus.. If breaks are suddenly applied your body falls forward because you were in motion with bus but it tries to be in motion when breaks are applied...

I lift a 20kg ball up 2.5 meters off the ground on Earth.

-Earth’s gravitational acceleration is about 9.8 m/s2.

How much gravitational potential energy does the ball have at this point? _____________
How much work did I do lifting up the ball? _____________________________________
If I lift the same ball the same distance on the Moon, then how much gravitational potential energy will it have? (Moon’s Gravity = 1.6 m/s2) ____________________________________

Answers

Answer: How much gravitational potential energy does the ball have at this point? At h = 20.4 m the gravitational potential energy of the ball reaches maximum.

How much work did I do lifting up the ball? As you are lifting the object you are doing work on the object. The work W done on an object by a constant force is defined as W = F·d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force.

using a diagram explain how acceleration can be obtained from a velocity time graph

Answers

Answer:

For any v-t graph the acceleration is the slope of the graph. For average acceleration in a time period ‘t’ consider the change in velocity in time t and divide it by the time t. For instantaneous acceleration you need to go into the realm of differential calculus.

Its obvious because more people are attracted to men soccer

I would say yes and no at the same time whatever way you are looking at it . Cause in a article it says men’s viewer ship in 2018 soccer is 3.5 billion views on television compared to the woman’s which was 1.1 billion views . So the more views the woman’s and men’s soccer gets the more they get paid . In which in a way that’s sets the woman’s pay way lower compared to the men’s.

0.0010 kg pellet is fired at a speed of 52.2 m/s at a motionless 3.3 kg piece of balsa wood. When the pellet
hits the wood, it sticks in the wood and they slide off together. With what speed do they slide? Round your
answer to the nearest thousandth.
m/s

Answers

The formula for momentum is p = m*v

The conservation of momentum suggests:

m*vi = m*vf (initial mass times initial velocity = final mass times final velocity or initial momentum = final momentum)

(0.0010)(52.2) = (0.0010 + 3.3)vf

vf = (0.0010)(52.2)/(0.0010 + 3.3) = 0.0522/3.301 ≈ 0.01581 m/s

To the nearest thousandth ≈ .016 m/s

Answers

Answer:

V = 12V, V = 8V

Explanation:

a) In this series circuit the equivalent resistance is

Req - R1 + R2

Req = 30 + 20

Eeq = 50 Ω

b) see attached

c) the circuit current is

i = V / Req

i = 20/50

How do I solve this arithmetic sequence?

Answers

Answer:

The 16ᵗʰ term of this sequence is 82

Step-by-step explanation:

Here,

First Term = a₁ = 9

Common Difference = (d) = 2

Now, For 16ᵗʰ term, n = 16

aₙ = a + (n - 1)d

a₁₆ = 7 + (16 - 1) × 2

a₁₆ = 7 + 15 × 5

a₁₆ = 7 + 75

a₁₆ = 82

Thus, The 16ᵗʰ term of this sequence is 82

A king orders a gold crown having a mass of 0.5 kg. When it arrives from the metalsmith, the volume of the crown is found to be 185 cm3. Is the crown made of solid gold?

Answers

Answer:

The crown is not made of solid gold.

Explanation:

Density ρ = M/V. M and V are given.

The density of the crown is (0.5 kg)/(185 cm3) * (106 cm3)/(1 m3) = 2.7*103 kg/m3.

The distance between the two nearest points on a wave where the particles are in phase is 2 m. What is the wavelength of the wave?

A. 1/2 m

B. 1 m

C. 2 m

D. 2 seconds

E. none of these

Answers

Answer:

Suppose that the wave equation is:

f(x) = A*cos(k*x)

The wave is in phase for two points x₁ and x₂ if:

f(x₁) = f(x₂)

And if these points are consecutive (for example, two consecutive peaks) then the wavelength of the wave is:

wavelength = x₂ - x₁

In this case, we know that the wave is in phase for two points that are 2 m apart.

Then we can use the points:

x₁ and x₂ such that:

x₂ = x₁ + 2m

We also know that these are the nearest points such that this happens, then we can assume that the points are consecutive.

Then the wavelength will be:

wavelength = x₂ - x₁ = (x₁ + 2m) - (x₁) = 2m

Then the wavelength is 2m.

The correct option is C.
