the average of the speed is 60
Answer:
<em>480m/s²</em>
Explanation:
Acceleration is the change in velocity of a body with respect to time;
Acceleration = change in velocity/change in time
change in velocity = 29,500 - 24,000
change in velocity= 5,500
Change in time = 55 - 5
change in time = 50secs
Substitute into the formula;
spaceships acceleration = 24000/50
spaceships acceleration = 480 m/s²
<em>Hence the spaceships acceleration is 480m/s²</em>
Answer:
Power of the electron beam in the x-ray tube is 2304 W
Explanation:
Given;
voltage of the electron beam in the x-ray tube, V = 144 kV = 144 x 10³ V
current of the electron beam in the x-ray tube, I = 16.0 mA = 16 x 10⁻³ A
Power is given as the product of voltage and current in a circuit.
Power of the electron beam in the x-ray tube, P = V x I
Power of the electron beam in the x-ray tube, P = 144 x 10³ V x 16 x 10⁻³ A
P = 2304 W
Therefore, power of the electron beam in the x-ray tube is 2304 W
n ecological terms, the carrying capacity of an ecosystem is the size of the population that can be supported indefinitely upon the available resources and services of that ecosystem. Living within the limits of an ecosystem depends on three factors:
<span>the amount of resources available in the ecosystem,the size of the population, and<span>the amount of resources each individual is consuming.</span></span>
