2 they vibrate and rotate at a fixed point
3 they gan heat energy in order for them to melt
4 particles are closely packed together
Answer:
8m
Explanation:
The magnitude m of a vector (x, y) is given by
m = -------------------------(i)
where;
x and y are the x- and y- components of the vector.
From the question;
m = 10m
x = 6m
Substitute these values into equation (i) as follows;
10 =
Solve for y;
<em>Find the square of both sides</em>
10² = 6² + y²
100 = 36 + y²
y² = 100 - 36
y² = 64
y = √64
y = 8
Therefore, the y-component of the position vector is 8m
Newton's laws are still very much used today for a number of applications ranging from planetary motion to the calculation of sprite velocities within computer games. Therefore the correct statement is: Newton's laws can explain the forces that occur between objects every day. Example forces include, gravity and friction.
Answer:
369.84 W
Explanation:
= Mass flow rate = 10.62 kg/s
v = Velocity of wind = 8 m/s
Power is given by
The power supplied is 339.84 W
If 30 W of this power is wasted that means 339.84+30 = 369.84 W is required
Answer:
Explanation:
= RMS voltage = 130 V
f = Frequency = 65 Hz
Instantaneous voltage is given by
at t = 0 v = 0
So, the function is
