The sign of the charged particle is positively charged.
<h3>What is potential difference?</h3>
- When a single charge is transported in an electric field, work is done by the potential difference (also known as electrical potential).
- There is potential energy stored in this charge that could flow when work is done on it.
- Voltage is the possibility of a single charge flowing. The need to flow increases with voltage.
- Here, voltage can be the potential differences.
The potential difference between the 2 points determines the movement of that particle. An electron moves from lower to higher potential which is negatively charged, and a positively charged particle moves from higher to lower potential.
Now, since the particle is moving from a point A having 160 v potential to point B having 100 v potential that is it is moving from higher potential to a lower potential therefore the particle will be a positively charged one.

Give u = start velocity
v = end velocity
v = u + at
50 = 400 + a*30
30a = -350
a = -116.67 m/
**Why the accecleration is negative number**
Because displacement, velocity, and acceleration are VECTOR QUANTITIES.
Vector Quantity must have direction.

too little body fat is a health risk
Explanation:
IF you do not have enough body fat you can have bad things happen to you
The equivalent formula for p = iv is the startfraction p over v endfraction = i
In physics, power measures the rate of transfer of electrical energy through a circuit per unit of time. It is denoted by P and is measured using the SI unit of power (watts or 1 joule/second). Electrical energy is usually supplied by batteries and produced by generators.
There are three types of power, true, reactive, and apparent, which are related in trigonometric form. This is called the power triangle. A power triangle that relates apparent power to active and reactive power. Power is measured in watts. One watt equals one joule per second.

Answer:
Mass of 17.854 kg is only attached to the spring
Explanation:
We have given time period in first case is 22 sec
Let initially mass is m
After 22 kg are added the period becomes 33 sec
Time period of spring mass system is
, here m is mass and k is spring constant
From the relation we can see that
Squaring both side
m = 17.584 kg
So mass of 17.854 kg is only attached to the spring
