Answer:
Potential difference (V) – is measured in volts (V).
A potential difference of 1 V means that 1 joule of work is done per coulomb of charge. ( 1 V = 1 J C-1) Potential difference in a circuit is measured using a voltmeter which is placed in parallel with the component of interest in the circuit.

Newton's first law. When the bus starts, Shelly is still at rest so she resists motion. (When the bus stops, she'll jolt forward)
Answer:
Resultant force = 17.02 N
Explanation:
As we assume the coefficient of friction is negligible, the normal force won't affect the resultant force.
As a result of this, the sine of the angle times the force of gravity on the 10 kg mass is equal to the resultant force, which is, force due to gravity = m × a = 10 kg × 9.8 m/s² = 98 N
98 sin(10)=?
Sin(10)= 0.1736
98 x 0.1736= 17.02 N.
Therefore, the resultant force = 17.02 N
The distance covered will be 0.301m.
firstly we will new to calculate acceleration (a).
we can do so using newtons first law of motion.
v=u + a × t
where
a is the acceleration
t is the time
from here we get
a=(v-u)/t
a=(4-0)/0.15
a=26.67m/s²
using newtons second law of motion
s=u.t+1/2at²
where s is distance travelled in t seconds.
we get,
s=0.301m
