The wheel of a stationary exercise bicycle at your gym makes one rotation in 0.670 s. Consider two points on this wheel: Point P

is 10.0 cm from the rotation axis, and point Q is 20.0 cm from the rotation axis. Find the speed of point P on the spinning wheel.

Answer:

0.938 m/s.

Explanation:

Given:

ω = 1 rev in 0.67 s

In rad/s,

1 rev = 2pi rad

ω = 2pi ÷ 0.67

= 9.38 rad/s

Rp = 10 cm

= 0.1 m

V = ω × r

= 9.38 × 0.1

= 0.938 m/s.

All of the planets and their satellites orbit the Sun in the same direction, and all their orbits lie near the same plane. True
MissTica

Answer:

True

Explanation:

The Sun rotates in the counterclockwise (CCW) direction when seen from its north pole. Since, the planets revolve around the Sun because of its gravity, the revolution of all the planets and their moons as seen from the north of the Sun is in CCW direction.

In fact most of the solar system bodies rotate in the same direction that is CCW. Some major exceptions to this are Venus and Uranus.

Almost all the planets and moons were made from the planetary disk around the Sun. Thus, they lie nearly in the same plane.

During nuclear fission and fusion, matter that seems to disappear is actually converted into
iris [78.8K]

Answer:

Energy (I need one more brainlist can i has?)

Explanation:

- Nuclear fusion occurs when two light nuclei fuse together into a heavier nucleus

- Nuclear fission occurs when a heavy, unstable nucleus breaks apart into two or more lighter nuclei

In both processes, the mass of the products is always smaller than the mass of the initial nuclei. This means that part of the initial mass has been converted into something else: into energy, which is released in the process.

The amount of energy released in the process can be calculated by using the famous Einstein's equivalence:

where m is the difference between the mass of the product and the initial mass of the nuclei, and c is the speed of light.

Is the energy of a wave is calculated by squaring the frequency of the wave?
Misha Larkins [42]
Nope.
Energy is directly proportional to frequency. and when you calculate energy, you multiply frequency with a constant number called "Planck's Constant"

E = hf

Hope this helps!

RAID 1 level should be  choosed by the administrator.

B) RAID 1

<u>Explanation:</u>

RAID 1 is commonly utilized with a couple of plates, however, it should be possible with additional, and would indistinguishably reflect/duplicate the information similarly over all the drives in the exhibit. RAID 1  requires at least two physical drives, as information is composed at the same time to two spots.

The drives are basically identical representations of one another, so on the off chance that one drive comes up short, the other one can dominate and give access to the information that is put away on that drive. The purpose of RAID 1 is principally for repetition, as you can totally lose a drive, yet at the same time keep awake and running off the extra drive(s).

Likewise, at least two circles are required for RAID 1 equipment usage. With programming RAID 1, rather than two physical circles, information can be reflected between volumes on a solitary plate.
