Answer:
Indian subcontinent
Explanation:
The Indian subcontinent is a southern region and peninsula of Asia which include seven countries. The seven countries in Indian subcontinent are Pakistan, Bangladesh, India, Bhutan, Maldives, Sri Lanka and Nepal. According to Wikipedia, about 55 million years ago, the Indian subcontinent has land mass that rifted from Gondwana and merged with the Eurasian plate.
Answer:
The brilliant galaxy centers are known as quasars. According to the astronomers quasars exists at the center o galaxies and in the center of galaxies there exists the black holes. Quasars are known as the brightest objects of the universe and they appear like a star in the telescopes.
Explanation:
Answer:
Option E is correct.
There must be a horizontal wind opposite the direction of the stone's motion, because ignoring air resistance when calculating the horizontal range would yield a value greater than 32 m.
Explanation:
Normally, ignoring air resistance, for projectile motion, the range (horizontal distance teavelled) of the motion is given as
R = (u² sin 2θ)/g
where
u = initial velocity of the projectile = 20 m/s
θ = angle above the horizontal at which the projectile was launched = 30°
g = acceleration due to gravity = 9.8 m/s²
R = (30² sin 60°) ÷ 9.8
R = 78.53 m
So, Normally, the stone should travel a horizontal distance of 78.53 m. So, travelling a horizontal distance of 32 m (less than half of what the range should be without air resistance) means that, the motion of the stone was impeded, hence, option E is correct.
There must be a horizontal wind opposite the direction of the stone's motion, because ignoring air resistance when calculating the horizontal range would yield a value greater than 32 m.
Hope this Helps!!!
Explanation:
a) P = IV
2000 W = I (230 V)
I = 8.7 A
b) The fuse must be rated for a higher current than the kettle, so use the 13A fuse.
c) Double insulation means there are two layers of insulation, insuring that the wires cannot touch the outer casing of the kettle and protecting the user from electrical shock.
d) V = IR
230 V = (8.7 A) R
R = 26.5 Ω
