What are the 3 Laws of Newtonian Mechanics

Katyanochek1 [597]

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction

Starting from rest, a 2.3x10-4 kg flea springs straight upward. While the flea is pushing off from the ground, the ground exerts

Harman [31]

Answer:

3.13 m/s

Explanation:

From the question,

Since the flea spring started from rest,

Ek = W................... Equation 1

Where Ek = Kinetic Energy of the flea spring, W = work done on the flea spring.

But,

Ek = 1/2mv²............ Equation 2

Where m = mass of the flea spring, v = flea's speed when it leaves the ground.

substitute equation 2 into equation 1

1/2mv² = W.................... Equation 3

make v the subject of the equation

v = √(2W/m)................. Equation 4

Given: W = 3.6×10⁻⁴ J, m = 2.3×10⁻⁴ kg

Substitute into equation 4

v = √[2×3.6×10⁻⁴ )/2.3×10⁻⁴]

v = 7.2/2.3

v = 3.13 m/s

Hence the flea's speed when it leaves the ground = 3.13 m/s

ASAP PLEASE! WILL GIVE BRAINLIEST ANSWER! The pictures below show the wavelengths and intensities of electromagnetic radiations

rjkz [21]

As per Weins displacement law the wavelength of light for which we get the peak of the graph is always inversely proportional to the temperature.

So we can say

$/lambda = \frac{b}{T}$

So here if temperature becomes more cool then wavelength will increase

here we know that

$\lambda_1 = 8500 A^o$

$\lambda_2 = 6000 A^o$

$\lambda_3 = 3500 A^o$

It means the hottest star out of all three is star 3

and coolest star is star 1

now if we star 2 becomes cooler then it means its temperature will go near to star 1 and hence it will more look like to star 1.

So correct answer is

it will look more like Star 1

15.3 comparing planetary motion compare and contrast the different types of planetary motion

Goryan [66]

There are only two types of planetary motion and these kinds are revolution and rotation. Revolution is the act of the planets in the solar system to move around or "revolve" around the sun while rotation is done in which the planet "rotates" on its axis. In addition, the earth revolves around the sun in 365 and 1/4 days.
