Answer:
Time = 0.187 secs
Explanation:
Parameters given:
Speed of hot air balloon = 1.60 m/s
Speed of toss = 10.7 m/s
Distance between passenger and friend at time of toss = 2m
To find the time given, we can simply divide the distance between the passenger and her friend by the speed of the toss. Mathematically,
Time = distance/speed
Time = 2/10.7
Time = 0.187 secs
Therefore, it takes 0.187 seconds for the camera to get to her.
Answer:Answer is A:The energy from the waves of light coming from bright lights would add up and free an electron.
Explanation:
Answer:
Explanation:
Given that,
g = 31 ft/s²
For every 1 lbf force, the compression is 1in
Then we can know the spring constant.
From Hooke's Law
F = Kx
K = F/x
K = 1/0.14
K = 7.143 lbf/in
Now, if the spring deflection is 1.8in
Then, the force applied is
F = kx
F = 7.143 × 1.8
F = 12.857 lbf
Now, this force is equal to the weight of the body
And weight of the body can be determined using.
W = mg
Therefore,
m = W/g
m = 12.857 / 31
m = 0.415 lb
The mass of the object is 0.415 pounds
