Answer:
10 dumbbells
Explanation:
First we need to calculate the gravity on the moon.
0.166 x 9.8 m/s² = 1.627 m/s² (the gravity is 0.166 times the Earth's gravity)
Taking this acceleration due to gravity, and multiplying it by the mass of a single dumbbell.
F = m x a
F = (225 kg) x (1.627 m/s²)
F = 366.075 N (the amount of force exerted by the dumbbell)
Taking the weightlifter's total upward force and dividing it by the force exerted by one dumbbell, we can calculate the amount of dumbbells that can be carried.
(3750 N) / (366.075 N)
= 10.24 dumbbells (but since there cannot be a fraction of a dumbbell, the answer is <u>10 dumbbells</u>).
Velocity would be an answer
The initial velocity of the ball is 0. Applying:
v = u + at
v = 0 + 229 x 0.08
v = 18.3 m/s
a)
Vx = Vcos(∅)
Vx = 18.3cos(52.3)
Vx = 11.2 m/s
b)
Vy = Vsin(∅)
Vy = 18.3sin(52.3)
Vy = 14.5 m/s
Answer:
Change in Velocity because
Explanation:
Remeber area is length times Width. In this case, the area under a accleraton vs time graph is Accleration Times Time. Which is velocity
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 .
