d) unaffected by the satellite's motion
Answer: an organic base, a phosphate group, and a sugar
Explanation:
B. 19.6 m
C. 1.8 m
D. 3.96 m
Answer: The ball will land at 19.6 m
Explanation:
To calculate the horizontal range of the ball, we use the formula:
where,
v = velocity of the ball = 14 m/s
= angle at which the ball is thrown = 51°
g = acceleration due to gravity =
Putting values in above equation, we get:
Hence, the ball will land at 19.6 m
b. liquid
c. water
d. plasma
The correct answer to the question will be that the electric force between them will be decreased.
EXPLANATION:
Let us consider the charge contained by A and B are denoted as Q and Q' respectively.
Let R is the separation distance between them.
As per Coulomb's law in electrostatics, the force of attraction or repulsion between the two charge bodies A and B will be -
Coulombic force F =
Here, is the permittivity of the medium in which the charges are present.
From above, we see that electric force is inversely proportional to the square of separation distance between them.
Mathematically it can be written:
As per the question, the distance between A and B is increased.
Hence, the electric force between A and B will be decreased.
