Answer:
<h2>
They would draw a total of 21.25 amperes</h2>
Explanation:
The total power consumed is
1200 W+ 750 W + 600 W= 2550 Watts
The formula relating the power consumed, the voltage and the current is given as
---------------1
given that the voltage supply is 120V
Answer:
I = 9.82 10⁻⁷ W / m²
Explanation:
The intensity of the sound wave is the energy of the wave between the order per unit area of the same
I = P / A = E / T A
the energy is calculated by integrating the mechanical energy in a period, where the mass is changed by the density and ‘s’ is the amplitude of the sound wave
I = ½ ρ v (w s)²
I = ½ 1.35 328 (2π 530 2.00 10⁻⁸)²
I = 221.4 (4.435 10⁻⁹)
I = 9.82 10⁻⁷ W / m²
Answer: 
Explanation:
Assuming there is only force in the y-component, the total net force 
acting on the parachute and the sky diver is:
(1)
Where:
is the drag force acting upwards
is the weight of the sky diver acting downwards, hence with negative sign
Then:
(2) This is the total net force excerted on the system parachute-sky diver, and the fact it is positive means is upwards
Now, according Newton's 2nd Law of Motion the force is directly proportional to the mass 
and to the acceleration 
of a body:
(3)
Where 
is the mass of the diver.
Substituting the known values and finding :
(4)
(5)
Finally:
This is the acceleration of the sky diver. Note it has a positive sign, which means its direction is upwards.
Based of the distance of each star, we can conclude that Star A must have a larger proper motion than Star B.
The given parameters;
- parallax of star A = 3.4 arc seconds
- parallax of star B = 1.7 arc seconds
The distance of each star form a Parallax is calculated as
Where;
d is the distance to star, [parsecs]
p is parallax, [arc seconds]
The distance of star A;
The distance of start B;
On average, it is known that a nearby star will have a large proper motion.
Based on the distance of each star calculated above, star A is nearer and it will have a larger proper motion that star B.

Answer:
b. 25W
Explanation:
The 25W bulb has 4 times the resistance of the 100W bulb, so 4/5 of the circuit voltage will develop across that bulb. The 352 volts applied will far exceed the rating of the 25W bulb, causing it to fail.
