Answer:

18.6 Ω

Explanation:

Resistance = \frac{Voltage}{Current}

But first we have to find the current.

Current = \frac{Power}{Voltage}

Power = 0.37W

Voltage = 2.60V

∴ Current = \frac{0.37}{2.60}

= 0.14 ( 3 significant figures)

Now we can find the resistance.

Resistance = \frac{2.60}{0.14}

= 18.6 Ω ( 3 significant figures)

There are eight men sitting on a couch. Three legs break and six men leave. How many legs are remaining
lutik1710 [3]

Explanation: Well, think about it if you see it on the logical end, there are 8 men that mean 16 legs. Then there are 4 legs of the couch as well that made it total of 20. If broken legs are of the men, then still the total will be 20 because the legs are still intact but 6 men left that means 12 legs are gone, if 3 legs break and 6 men leave. the number of legs remaining are 20–6*2–3=5....  so it's 5  I hope this helps! xoxo

What is a centripetal acceleration of a point on a bicycle wheel of a radius of 0.70 m when a bike is moving 8.0 m/s
Furkat [3]

Answer:

The acceleration of a point on the wheel is 11.43 m/s² acting radially inward.

Explanation:

The centripetal acceleration acts on a body when it is performing a circular motion.

Here, a point on the bicycle is performing circular motion as the rotation of the wheel produces a circular motion.

The centripetal acceleration of a point moving with a velocity v and at a distance of r from the axis of rotation is given as:

a=\frac{v^2}{r}

Here, v=8\ m/s,r=0.70\ m

∴ a=\frac{8}{0.70}=11.43\ m/s^2

Therefore, the acceleration of a point on the wheel is 11.43 m/s² acting radially inward.

An asteroid exerts a 360-N gravitational force on a nearby spacecraft. If the spacecraft moves to a position three times as far
KIM [24]

Answer:

40 N

Explanation:

The gravitational force between the asteroid and the spaceship is given by:

F=G\frac{mM}{R^2}

where

G=6.67\cdot 10^{-11} m^3 kg^{-1} s^{-2} is the gravitational constant

M is the mass of the asteroid

m is the mass of the spaceship

R is the distance between the asteroid and the spaceship

The initial force is equal to:

F=G\frac{mM}{R^2}=360 N

Later, the spaceship moves to a position 3 times as far from the center of the asteroid, so R' = 3R. Therefore, the new force will be

F'=G\frac{mM}{R'^2}=G\frac{mM}{(3R)^2}=G\frac{mM}{9R^2}=\frac{1}{9}F

so, the force is decreased by a factor 9. Since the initial force was F=360 N, the new force will be

F'=\frac{360 N}{9}=40 N
