Here is the answer. In order for us to get the speed, we are just going to use the formula speed is equal to distance over time. Given that the distance s 200m and the time is 25s, this would give us the answer of 8m/sec. Hope this answers your question.
Answer:
Explanation:
Current drawn by electric heater = power/volt =1500/120 = 12.5 A.
current drawn by hair drier at 600 watt = 600/120 =5 A
current drawn by hair drier at 900 watt = 900/120 = 7.5 A.
Total current drawn by heater and hair drier used at 900 watt
= 12.5 + 7.5 = 20 A
Breaking current =20 A
So fuse will trip at this point .
Answer:
μ =tanθ
Explanation:=
The ratio of the force of static friction and the normal reaction is equal to tanθ. F=mgsinθ. R = mgcosθ.
μ=tanθ
Answer:
A.
Explanation:
X represents the transmitting power Modulates (amplitude or frequency am/fm), amplifies the signal, transmitting it out at whatever direction the antenna is set up for.
