Explanation:
It is given that,
A planet were discovered between the sun and Mercury, with a circular orbit of radius equal to 2/3 of the average orbit radius of Mercury.
Mass of the Sun, 
Radius of Mercury's orbit, 
Radius of discovered planet, 
Let T is the orbital period of such a planet. Using Kepler's third law of planetary motion as :
T = 4135214.625 s
or
T = 47.86 days
So, the orbital period of such a planet is 47.86 days. Hence, this is the required solution.
Kinetic Energy is calculated by KE= 1/2mv2
Answer: K
Explanation:
From the temperature readings given, we should note that 0°F is thesame as 32°C. Therefore, 0°C is colder than 0°F.
We should note that at 0K which is written as K, it is the coolest and it is often called the absolute zero because at this degree, there can't be anything that's colder.
Therefore, the answer is K
Answer:
The answer is "distance = Vx × t"
Explanation:
To determine how far the golf ball traveled, the formula for velocity can be used, which is
velocity (m/s) = distance (m) ÷ time (s)
Make distance the subject of the formula
distance = velocity × time
Thus, where velocity is Vx and time is t
distance = Vx × t
The unit of the distance will be in meter (m)
Answer:
B.
Explanation:
In a scientific context, “pure” denotes a single type of material. Ostensibly, compounds contain more than one type of material. Yet both compounds and elements are considered pure substances. Pure compounds are created when elements combine permanently, forming one substance.
