Answer:
7.5 Ω
Explanation:
Voltage = Current x Resistance
(V = IR)
240 = 32 R
R = 240 / 32
= 7.5 Ω
Pluto has a shape that is nearly round, and it orbits the Sun. It has five known moons. It is called a dwarf planet and not a planet because its orbit is not cleared of like-sized or larger objects
Answer: Option B
<u>Explanation:</u>
According to the International Astronomical Union (IAU), Pluto has been mentioned as Dwarf Planet as it doesn't hold the standardisation to be counted as a Planet.
According to the standard criteria, a planet must have been surrounded by the orbit of the Sun, it must have significant mass to have a gravitational pull and hence, circular shape, and should have isolated surrounding.
But, Pluto has various celestial bodies in its vicinity that are larger in size. Hence, as concluded by the Union, any celestial body that does not has clear surrounding, is regarded as Dwarf Planet just like Pluto.
Answer:
Explanation:
The acceleration experimented while taking a curve is the centripetal acceleration 
. Since 
, we have that: 
They take the same curve, so we have: 
Which means: 
And finally we obtain:
Her magnitude of deceleration on the ice would be 15.126m/s
Answer:
B
Explanation:
the amplitude is the distance from the resting point to the crest/trough.
