1,000 W = 1 kW
100 W = 0.1 kW
(0.1 kW) x (6 h) = 0.6 kWh <=== energy
(0.6 kWh) x (£0.1359/kWh) = £0.0815 <=== cost of it
The y-component of the velocity of the carrion is equal to zero. That being said, the time it takes for the carrion to reach the ground (as close as possible to the fox) can be calculated through the equation,
d = Vot + 0.5gt²
where d is the distance, Vo is initial velocity (in this case, zero), g is the acceleration due to gravity (9.8 m/s²). Substituting the known values,
14 = 0.5(9.8)(t²)
t = 1.69 seconds
Since the horizontal component of the velocity is 1.5 m/s, the distance from the base of the tree to the point where the carrion will fall is equal to,
(1.5 m/s)(1.69 s) = 2.535 m
We add this to the given distance of the fox from the base of the tree to determine the distance of the fox from the carrion.
total distance = 2.535 m + 7 m = 9.535 m
Given that the time it takes for it to travel would only be 1.69 seconds, the speed would then be,
speed = (9.535 m) / (1.69 s) = 5.64 m/s
<em>ANSWER: speed = 5.64 m/s</em>
I belive it could be 6.5 but I could be wrong
Air bags are kept in the steering wheel or
dashboard and expand during a serious collision, usually a front collision that
occurs at over 10 mph. To do its important job, an air bag comes out of the
dashboard at up to 200 mph, faster than the blink of an eye. It is estimated
around 10 inches of space to inflate. The force of an air bag can hurt those
who are too close to it. Driver and front seat passengers should be
moved as far back as practical, mainly people of short built. It is highly suggested
that you be seated no less than 10 inches away from the air bag. Therefore, the answer is letter b.
Answer:
Explanation:
B. Turn the steering wheel while the car is moving.
causes centripetal acceleration.
C. Press the gas pedal while the car is stopped.
causes forward acceleration.
D. Press the brake pedal while the car is moving.
causes rearward acceleration.
