Answer:
primary voltage/secondary voltage = number of turns on primary coil/number of turns on secondary coil
V1/V2= N1/N2
1.5/5 = 150/N2
0.3 = 150/N2
N2= 150/0.3
N2 = 500
i d k I'm right or wrong but i tried.....lemme know if it's correct!!
Answer:
d = 2*0.87 = 1.75 cm
Explanation:
by using flow rate equation to determine the speed in larger pipe
= 591.10 cm/s
= 5.91 m/s
by Bernoulli's EQUATION
solving for v2
v2 = 10.53 m/s
diameter can be determine by using flow rate equation
r = 0.87 cm
d = 2*0.87 = 1.75 cm
Answer:
Four times higher
Explanation:
F- G (m1 x m2)/ r^2
if r 1 = 2 and r 2 = 1 therefore F = G (m1 x m2)/ 1^2 is 4 times higher than
2^2 since G and m1 and m2 remained the same
Answer: False
Explanation:
The statement that the environment affects people, but people don't affect the environment is incorrect. It should be noted that people also affect the environment.
Some of our impact on the environment include pollution, deforestation, overpopulation, burning of fossil fuels etc. Thus has resulted in changes such as erosion, climate change, etc.
