Answer is A because the speed and velocity would change. Think of it as GTA, your going 30+ miles per hour and you take a left turn, the speed and velocity would change in an instant..
Hope this helped.
Answer:

Explanation:
From the question we are told that:
Potential difference 
New Capacitor 
Generally the equation for Capacitor capacitance is mathematically given by

Generally the equation for New p.d' is mathematically given by




Answer:
4 times the mass of Earth
Explanation:
= Mass of Earth
= Mass of the other planet
r = Radius of Earth
2r = Radius of the other planet
m = Mass of object
The force of gravity on an object on Earth is

The force of gravity on an object on the other planet is

As the forces are equal

So, the other planet would have 4 times the mass of Earth
Answer:
44.7 N
Explanation:
The gravitational force between the objects is given by:

where
G is the gravitational constant
m and M are the masses of the two objects
r is the distance between the centres of the two objects
In this problem, we have:
is the mass of the sphere
is the Earth's mass
is the Earth's radius, while h=310 km is the altitude of the sphere, so the distance of the sphere from Earth's centre is

Substituting into the equation, we find

Answer:
beat frequency = 13.87 Hz
Explanation:
given data
lengths l = 2.00 m
linear mass density μ = 0.0065 kg/m
String A is under a tension T1 = 120.00 N
String B is under a tension T2 = 130.00 N
n = 10 mode
to find out
beat frequency
solution
we know here that length L is
L = n ×
........1
so λ =
and velocity is express as
V =
.................2
so
frequency for string A = f1 = 
f1 = 
f1 =
and
f2 =
so
beat frequency is = f2 - f1
put here value
beat frequency =
-
beat frequency = 13.87 Hz
