Answer:
C. the time interval for stopping is greater.
Explanation:
As the egg falls onto the grass, it takes a a greater amount of time for it to stop, and thus the force that is being applied to it is in increments; there is never enough force applied on the egg for it to break. That's why the egg doesn't break when it lands on the grass.
In contrast, when the egg is dropped on the road, <em>all of the force that is being applied by the road on the egg is in the tiny interval when the egg touches the road</em>, That force is large enough to break the egg because it is being applied in a tiny amount of time. That's why the egg dropped on the road breaks.
<em>So here is the rule of thumb: if you don't want to break your things but still want to drop them, drop them such that it takes some for them to stop—because force will applied to them gradually. </em>
Answer:
A) Have more coils of wire
F) Use a more powerful battery
Answer:
TDR means Timeout Detection and Recovery.
Explanation:
TDR is a feature of the Windows operating system which detects response problems from a graphics card, and recovers to a functional desktop by resetting the card. If the operating system does not receive a response from a graphics card within a certain amount of time (default is 2 seconds), the operating system resets the graphics card.
Answer:
1.65 kg.m/s
Explanation:
mass of ball (m) = 0.13 kg
initial speed (u) = 18 m/s
acceleration due to gravity (g) = 9.81 m/s^{2}
angle of projection (p) = 90°
to find the momentum half way to its maximum height we first have to know the maximum height, and the velocity at the maximum height.
maximum height (h) =
maximum height (h) = = 16.53 m
velocity at half the maximum height (v) can be gotten from the equation of motion
( the negative sign is because the ball is moving upwards)
v =
v= 12.72 m/s
momentum of the ball half way to its maximum height = mass x velocity = 0.13 x 12.72 = 1.65 kg.m/s
Answer: L.M = 34.69
Area of the bar = 25835m^2
Explanation: To design a bar that can withstand temperature at 773K for 10years, we need to calculate and know:
1) the Larson Miller value
2) rupture time
3) creep rate
4) stress and load.
