Answer:
Explanation:
Magma contains dissolved gases, which provide the driving force that causes most volcanic eruptions. As magma rises towards the surface and pressure decreases, gases are released from the liquid portion of the magma (melt) and continue to travel upward, and are eventually released into the atmosphere.
Answer:
9.01amp
Explanation:
Power = V^2/R
Given that v = 11volts, P = 99watts
99 = 11^2/R
11×11 = 99R
121= 99R
R = 121/99
R= 1.22ohms
From ohms Law; V = IR
11volts = I × 1.22ohms
I = 11/1.23
I = 9.01 amp
Answer:
Power, P = 112500 watts
Explanation:
It is given that,
Mass of the car, m = 1500 kg
Initial velocity of the car, u = 0
Final velocity of the car, v = 30 m/s
Time taken, t = 6 s
The minimum average power delivered by the engine is given by :
P = W/t
Where
W = work done
t = time taken
Work done = change in kinetic energy
So, 

P = 112500 watts
So, the minimum average power delivered by the engine is 112500 watts. Hence, this is the required solution.

<span>The physical property that the symbol IencI represents is the net of the current that flows through the Amperian loop. The Amperian loop is not actually present, but instead is the area around a current that would exist assuming that Ampere's law is accurate. It is essentially an invisible loop that surrounds the current and represents the physical property of the current.</span>
