I am pretty sure that <span>the following whihc cannot be determined by looking at the phase diagram is definitely </span>D. system pressure. I consider this one to be correct because only this point is not included into<span> phase diagram and can't be determined itself. Hope it will help! Regards!</span>
Answer:
the same time
Explanation:
since the speed of light is very fast (3×10^8 ms^-1) the difference in time arrived from firecrackers A and B to Bob is negligible, and our brain can distinguish such small time difference,l.
<u>Given data:</u>
Voltage (V) = 120 V,
Power (P) = 50.4 Watts,
current flowing (I) = ?
Power is nothing but the rate of doing work. Hence W/t represents electric Power (P).
Electric Power (P) = V.I Watts
This equation can be used to calculate the power consumption by any electrical device that is connected in a circuit.
In the given question, we need to determine the Current flowing through the circuit(bulb).
From the equation,
P = V.I Watts
50.4 = 120 × I
I = 50.4/120
I = 0.42 Amp
<em>Current flowing through the circuit is 0.42 Amperes. </em>
Answer:
a) 378Ns
b) 477.27N
Explanation:
Impulse is the defined as the product of the applied force and time taken. This is expressed according to the formula
I = Ft = m(v-u)
m is the mass = 70kg
v is the final velocity = 5.4m/s
u is the initial velocity = 0m/s
Get the impulse
I = m(v-u)
I = 70(5.4-0)
I = 70(5.4)
I = 378Ns
b) Average total force is expressed as
F = ma (Newton's second law)
F = m(v-u)/t
F = 378/0.792
F = 477.27N
Hence the average total force experienced by a 70.0-kg passenger in the car during the time the car accelerates is 477.27N
Oofffffffffffffffffffffffff
