Answer:
Option A
Incandescent
Explanation:
While low pressure sodium light bulb produces the highest lumens per watt, it's incandescent light bulb that produces the lowest lumens per watt. It's important to note that incandescent lights operate at the same wattage as fluorescent lights to give out same amount of light but they produce the lowest lumens per watt compared to fluorescent lights.
Answer;
how fast or slow something is done.
Explanation;
The term rate refers to how fast or slow something is done. For example; a higher rate shows how fast something is being done or is taking lace, lower rate shows how slow something is being done.
In other words it is a quantity measured with respect to another measured quantity; for instance; a rate of speed of 60 miles per hour.
Answer:
option (b)
Explanation:
Let the resistance of each resistor is R.
In series combination,
The effective resistance is Rs.
rs = r + R + R + .... + n times = NR
Let V be the source of potential difference.
Power in series
Ps = v^2 / Rs = V^2 / NR ..... (1)
In parallel combination
the effective resistance is Rp
1 / Rp = 1 / R + 1 / R + .... + N times
1 / Rp = N / R
Rp = R / N
Power is parallel
Rp = v^2 / Rp = N V^2 / R ..... (2)
Divide equation (1) by equation (2) we get
Ps / Pp = 1 / N^2
Hello!
Using Hooke's law, F spring=k delta x, find the distance a spring with an elastic constant of 4 N/cm will stretch if a 2 newton force is applied to it.
Data:
Hooke represented mathematically his theory with the equation:
F = K * Δx
On what:
F (elastic force) = 2 N
K (elastic constant) = 4 N/cm
Δx (deformation or elongation of the elastic medium or distance from a spring) = ?
Solving:
simplify by 2
Answer:
B.) 1/2 cm
