Answer:
B. You would weigh the same on both planets because their masses and the distance to their centers of gravity are the same.
Explanation:
Given that Planets A and B have the same size, mass.
Let the masses of the planets A and B are 
and 
respectively.
As masses are equal, so 
.
Similarly, let the radii of the planets A and B are 
and 
respectively.
As radii are equal, so 
.
Let my mass is m.
As the weight of any object on the planet is equal to the gravitational force exerted by the planet on the object.
So, my weight on planet A, 
my weight of planet B, 
By using equations (i) and (ii),
.
So, the weight on both planets is the same because their masses and the distance to their centers of gravity are the same.
Hence, option (B) is correct.
The basic steps are simple but careful
planning is needed. Sand dune restoration should be designed to create a dune that matches the
existing natural dune pattern in the area. You can help
speed up nature's work by using sand fences and dune
plants to collect sand more rapidly. Or in a different way, wind would bring more sand to create a dune. hope this helped, have an amazing day :)
Answer:
Option B is correct.
Explanation:
Potential energy or chemical potential energy is used to Cook food which is then converted into thermal energy. The type of energy used also depends upon the type of cooking appliances used.
For e.g. stove convert potential energy to thermal energy.
Answer:
17 kJ
Explanation:
q = mCΔT
q = (55 kg) (4.184 kJ/kg/K) (360 K − 285 K)
q = 17,000 J
The correct answer to the question is : The ostrich is motion.
EXPLANATION:
As per the question, the momentum of ostrich P = 5400 Kg. Km/hr.
The mass of the ostrich m = 120 Kg.
The momentum of a body is defined as the product of mass with velocity.
Mathematically P = mv.
The velocity of the ostrich v is calculated as -
v = 
= 
= 45 Km/hr
Hence, the ostrich is in motion as it is moving with a velocity of 45 Km/hr.
