To solve this problem we will apply Newton's second law, which indicates that the force is equivalent to the product between mass and acceleration, so
Here,
F= Force
m = Mass
a = Acceleration
Rearranging to find the mass we have,
The value of the acceleration is
Replacing to find the mass,
Now in ponds this value is
Therefore the mass of the spacecraft is 52.8lb
Answer:
Well, Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy..
Explanation:
Answer:
so the distance between two points are
Explanation:
Surface charge density of the charged plane is given as
now we have electric field due to charged planed is given as
now we have
now for the potential difference of 100 Volts we can have the relation as
Answer:
The distance of the first bright fringe is given as
The distance of the second dark fringe from the central bright fringe is given as
Explanation:
From the question we are told that
The slit separation distance is
The distance of the slit from the screen is
The wavelength is
For constructive interference to occur the distance between the two slit is mathematically represented as
Where m is the order of the fringe which has a value of 1 for first bright fringe
Substituting values
For destructive interference to occur the distance between the two slit is mathematically represented as
m = 2
so the formula to get the dark fringe is
Now substituting values
Answer:
D).
Explanation:
As we know that temperature scale is linear so we will have
now we have
so the relation between two scales is given as
now we know that in kelvin scale the absolute temperature is 600 K
so now we have
so correct answer is
D).
