Answer:
4.5kgm/s
Explanation:
Change in momentum is expressed as
Change in momentum = m(v-u)
M is the mass
V is the final velocity
u is the initial velocity
Given
m=0.45kg
v = 30m/s
u = 20m/s
Substitute
Change in momentum = 0.45(30-20)
Change in momentum = 0.45×10
Change in momentum = 4.5kgm/s

Answer for the question is given in the attachment.
Explanation:
The electric furnace will consume 9600 watt of power.
To find the answer, we need to know about the electric power.
<h3>What's the electric power?</h3>
- Electric power is defined as the product of voltage and current.
- Mathematically, power= V×I
- Its si unit is watt.
<h3>What will be the power consumed by an electric furnace that draws 40A with an applied voltage of 240V?</h3>
The power = 240×40 = 9600 watt
Thus, we can conclude that the power consumption of the electric furnace is 9600 watt.
