Answer:
0.29713 m/s
Explanation:
m = Mass of person
g = Acceleration due to gravity = 9.81 m/s²
v = Velocity
r = Radius = 18 mm
By balancing the forces in the system we have
The velocity of the coaster is 0.29713 m/s
Answer:
Option E, double the charge to 2, is the right answer.
Explanation:
Given the electric field at point = P
The point charge = Q
Distance =R
Magnitude = E
Due to a certain charge, the magnitude of the electric field at a point is defined as:
Here, we can see that E is proportionate to Q and 1/r^2
Hence, double the charge to 2 and at the same time reduce the distance to /2 will half the E
Therefore, doubling the charge will doubling E
So the answer is (e) is correct.
Answer:
A the force was in their direction
Digital signals are advantageous over analog signals because they are easily reproducible and convey information with little interference.
<h3>What are analog and digital signal?</h3>
Analogs signals are signal which are continuous whereas digital signals are signal which are not continuous but are separated by time.
Use of digital signals are most common because they have certain advantages over analog signals.
Some advantages of digital signals over analog signals include:
- Digital signals can convey information with less noise and interference.
- Digital circuits can be easily reproduced
Therefore, Digital signals are advantageous over analog signals because they are easily reproducible and convey information with little interference.

The correct is D.
Explanation: The specific heat is defined as heat required to raise the temperature of a unit mass by one degree. Greater the specific heat, more is the heat required to raise the temperature for equal mass. So, the temperature of the material with lowest specific heat will increase the most for the same amount of heat energy.
