Answer:
62.7 VA
Explanation:
The apparent power (power supplied by the source) of an AC circuit is determined by
The impedance(Z) depends on the frequency, but in this case it is given to us that it is 102 ohms at this frequency.
So:
Recall Newton's second law:
F = ma
F is the force exerted on the object.
m is the mass of the object.
a is the acceleration of the object.
Given values:
F = 75 N
m = 15 kg
Substitute the terms in the equation with the given values and solve for a:
75 = 15×a
<h3>a = m/s²</h3>
The voltage in a circuit is given by the expression , V = IR , Where I is the current inbthe circuit and R is the resistance of circuit.
In this case I = V/R
In this circuit voltage V = 10 volt
Resistance of the circuit = 20 ohm
So current , I = 10/20 = 0.5 amperes
So if a 10-volt battery is placed across a 20-ohm resistance, the current will be 0.5 amperes
Light receptors within the eye transmit messages to the brain. This produces the familiar sensations of color. Newton observed that color is not inherent in objects. Instead, the surface of an object reflects some colors and absorbs all the others. We perceive only the reflected colors.
Answer: To "hole the ball: on the very first putt is requered is required a 7.08 m displacement at an angle 11.03° north of east.
Explanation:
Let's add each stroke as vectors
- Due east direction: 4.6 m + 2.5 cos(20°) m ≅ 6.95 m
- Due north direction: 0.5 m + 2.5 sin(20°) m ≅ 1.35 m
So the total displacement is
and the direction
