Small robots that can move around on the surface of a planet are called space shuttles.

1 answer:

5 0

No. "Shuttle" has been pretty much used to indicate shuttling
between Earth and Earth-orbit.

The devices that have tooled around on the surface of Mars
have been referred to as "rovers". That was also the nickname
of the buggy on which the Apollo astronauts moved around on
the Moon in the early 1970s ... the "lunar rover".

A ruler of length 0.30m is pivoted at its centre. Equal and opposite forces of magnitude 2.0N are applied to the ends of the rul

kow [346]

Answer:

0.3858 Nm

Explanation:

The torque of the couple is the dot product of the force vector and the couple vector from 1 end of the ruler to the center. This equals to the product of their magnitude times the cosine() of the angle made by their direction:

$T = \vec{F} \cdot \vec{s} = Fscos(50^0) = 2 * 0.3 * 0.643 = 0.3858 Nm$

Two strong magnets were brought close to each other. They were repelling each other. Explain what must have happened.

r-ruslan [8.4K]

When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract.

Identify the procedure to determine a formula for self-inductance, or inductance for short. Using the formula derived in the tex

kompoz [17]

Answer:

L = 0.0319 H

Explanation:

Given that,

Number of loops in the solenoid, N = 900

Radius of the wire, r = 3 cm = 0.03 m

Length of the rod, l = 9 cm = 0.09 m

To find,

Self inductance in the solenoid

Solution,

The expression for the self inductance of the solenoid is given by :

$L=\dfrac{\mu_o N^2 A}{l}$

$L=\dfrac{4\pi\times10^{-7}\times(900)^{2}\times\pi(0.03)^{2}}{0.09}$

L = 0.0319 H

So, the self inductance of the solenoid is 0.0319 henries.
