If the size of the charge value is tripled for both of twopoint charges maintained at a constant separation, the mutual forcebet
1 answer:
Answer:
a) 9.0
Explanation:
The force between two point charges, obeys Coulomb's Law, which can be written as follows:
As it can be seen, if the separation between the charges remains the same, the new value of the force will be directly proportional to the product of the charges.
If both charges are tripled, the mutual force between them will be changed in a factor equal to 3.0*3.0 = 9.0

Explanation:
given,
frequency of the alarm = 872.10 Hz
after passing car frequency she hear = 851.10 Hz
Speed of sound = 343 m/s
speed of the jogger = ?
speed of the
v_o = 872.1 - 10.5
The speed of jogger
v = 4.18 m/s
Answer:
Explanation:
what is the smallest crater that each of these telescopes could resolve on our moon?
For moon ;
s = 3.8 × 10 ⁸ m
y = 1.22 λs/D
where;
λ = 400 nm = 400× 10 ⁻⁹
D = 2.4 m
The smallest crater for the hubble space is calculated as follows:
For Aceribo ;
y = 1.22 λs/D
where :
λ = 75 cm = 0.75 m
D = 305 m
