Answer:
Explanation:
The formula for variation in the value of g due to height h is given by the following relation .
g₁ = g₀ ( 1 - h / R )
g₁ and g₀ are value of acceleration due to gravity at height h from surface and at surface and R is radius of the earth .
R = 6370 km , h = 489 km ( given )
g₁ = g₀ ( 1 - 489 / 6370 )
= .923 g₀
g₁ in percent terms = .923 x 100
= 92.3 % .
Answer:
The angle will be 0 . The angle between the incident ray and the mirror is called angle of incidence while the angle between reflected ray and the normal is called angle of reflection. Here, the a ray of light is incident normally on a plane mirror.
Explanation:
Explanation:
It is known that the molecular weight of ammonia (
) is as follows.
Molecular weight () = 
= 17
(a) Therefore, we will calculate the mass as follows.
= 8500 g
Now, formula to calculate weight of the system in N is as follows.
Weight = mass × g
= 
= 83.3 N (1 
= 1 N)
Hence, the weight of the system is 83.3 N.
(b) Relation between specific volume and number of moles is as follows.
Therefore, calculate the specific volume as follows.
= 12 
Also,
v = 
= 0.705882 
Therefore, we can conclude that the value of specific volume is 12 and 0.705882 .
Answer:
Subatomic particles are particles that are smaller than atoms. They can be a composite particle, such as protons and neutrons or they also can be elementary particles, which are not made of any other particles.
<span>You should stay on the top of the boat, this will help rescuers find you because a boat is easier to find than a small body in a large ocean. Never swim away from the boat you could catch a cold and/ or get hypothermia or drift far away from where you were last seen. This will make the search much harder.</span>
