A motorcycle sees a branch in the road, and hits the brakes, slowing down at -6.42m/s^2. If it takes him 2.85s to stop, what was
Alborosie

Answer:

The initial velocity of the motorcycle is 18.29 m/s.

Explanation:

Given that,

When a motorcycle hits the brakes, its final speed becomes zero.

Acceleration of the motorcycle, a=-6.42\ m/s^2

Time taken to stop, t = 2.85 s

We need to find the initial velocity of the motorcycle. The first equation of kinematics is given by :

v=u+at\\\\-u=at\\\\u=6.42\times 2.85\\\\u=18.29\ m/s

So, the initial velocity of the motorcycle is 18.29 m/s.

Fynjy0 [20]

Answer:

6.65*10^{27}W

Explanation:

The relationship of intensity:

I=\frac{P}{4\pi r^{2} }

Intensity: I=14W/m^{2}

radius: r=6.00*10^{12} m

Power is unknown

Now we can apply the formula

I=\frac{P}{4\pi r^{2} }\\P=I(4\pi r^{2})\\P=14.7(4*\pi *(6.00*10^{12} )^{2} )\\P=6.65*10^{27} W

if it is known that the toggle clamp is a machine, what assumptions can be made about it? check all that apply. (you must provid
muminat

A toggle clamp is a device that you employ, often but not exclusively as part of a production process, to firmly place components or parts in place.

Explain about toggle clamp.

A toggle clamp's main characteristics are its rapid action and ability to be easily turned on and off by an operator. Toggle clamps also lock in place firmly. Because of this, toggle clamps are frequently employed in production lines where components need to be held firmly and quickly removed during routine manufacturing procedures.

Toggle clamps with standard or light action are often constructed from components of pressed steel that have been zinc-plated.

Depending on the setting in which you work, Stainless Steel is another alternative for Toggle Clamp production. Stainless steel toggle clamps are frequently used in regulated areas where hygiene is crucial, such as the food industry and the pharmaceutical business.

Orbital velocity is the average speed of a planet moving through space in its orbit around the sun. Which of the following plane
labwork [276]

The force of gravity is equal to the mass times centripetal acceleration.

Fg = m v^2 / r

The force of gravity is defined by Newton's law of universal gravitation as:

Fg = mMG / r^2

Therefore:

mMG / r^2 = m v^2 / r

MG / r = v^2

v increases as r decreases. So the planet with the smallest orbit (closest to the sun) will have the highest orbital velocity. Of the four options, that's Mercury.
