Answer:
40.22 days
Explanation:
Given data:
Closest approach distance between Mars and Earth = 56 million km = 56 × 10⁶ km
Speed of the spaceship = 58000 km/h
Now, the time (t) is calculated as:
time = Distance / speed
on substituting the values, we get
t = 56 × 10⁶ km / (58000 km/h)
or
t = 965.517 hours
or
t = 965.517 / 24 days = 40.22 days

I'm not sure..but please refer to your teacher later.
Answer: Based on Newton's First law of motion (where inertia is involved), smooth ice increases the forceused to accelerate the hockey puck.
Explanation;
- smooth ice reduces the resistances between the surface of the figure skates and the ice itself.
- based on inertia theory ; the heavier the weight, the larger the inertia.. which explains it takes alot of force to move a heavier object than the lighter ones.. it also hard to *stop* the motion of heavier objects than the lighter ones.
- now let's look at the design of the player shoe itself, they have a sharp blade at the bottom of the figure stakes.. which takes us to the law of the force.. the smaller the surface area, the more forces acting on it. So, players force (weight, F= mg) acts on the tip of the blade and on the ice
- high inertia (run fast) and high force (attack opponent and pass puck) enables them to perform well in playing hockey
- Thus if there's no resistance and the inertia of the player is high then they could run and pass the puck quickly
Answer:
Explanation:
It is given that,
Weight of the person on Earth, W = 818 N
Weight of a person is given by the following formula as :
g is the acceleration due to gravity on earth
m = 83.46 kg
The mass of an object is same everywhere. It does not depend on the location.
Let W' is the weight of the person on the surface of a nearby planet, W' = 5320 N
g' is the acceleration due to gravity on that planet. So,
So, the acceleration due to gravity on that planet is 
. Hence, this is the required solution.
