I think that the answer to this is a. hope this helps
weight of 30 Kg object= 300 N
Explanation:
Weight= m I
m= mass=30 kg
I= gravitational filed strength= 10 N/kg
weight=30 (10)
weight=300 N
-- Earth's average distance from the sun is about 93 million miles.
-- Mars' average distance around the sun is about 142 million miles.
-- So, as both planets travel in their orbits around the sun, the distance
between them changes, between (142 - 93) = about 49 million miles
and (142 + 93) = about 235 million miles.
Answer:
ALMA is a trans-formative radio telescope that can study cosmic light that straddles the boundary between radio and infrared. Most objects in the Universe emit this kind of energy, so the ability to detect it has been a driver for astronomers for decades.
Explanation:
Answer:
v = 14.87 m/s
Explanation:
Given that
Initial speed ,u= 9.2 m/s
θ = 4°
Distance d= 100 m
Lets speed after traveling 100 m is v.
From the diagram
h = d sinθ
h = 100 sin 4°
h = 6.97 m
We know that
v = 14.87 m/s
