Answer:
(a) =34.0J
(b) = 13.038m/s
(c) =
Explanation:
(a) mass (m) =0.45kg
Height(h) =8.5m
Gravity (g) =10m/s^2
But P. E (Potential Energy) = mass × gravity × height
P. E = 0.45×10×8.5
P. E = 34.0J
(b) using v^2=u^2 - 2gs
Where v = final velocity
u= initial velocity
g = gravity
s =distance
But at maximum height <u>v</u><u> </u>=0
0^2= u^2 - 2gs
Transpose u^2 we have
u^2 = 2gs
u^2 = 2×10×8.5
u^2 = 170
u = square root of 170
u = 13.038m/s
Answer:
At 6 minutes, the soil temperature at a 45° angle of insolation is higher than at 0°.
At 15 minutes, the soil temperature at a 90° angle of insolation is higher than at 45°
Explanation:
When a new path of lesser resistance is made for an existing circuit a(n) short circuit occurs.
<h3>
What is short circuit?</h3>
An electrical circuit short circuit is when two nodes that are supposed to be connected at different voltages make an improper connection. This leads to an electric current that can damage circuits, cause overheating, fire, or explosions, and is only constrained by the network's remaining nodes' equivalent Thevenin resistance. While short circuits are typically the result of a failure, they can occasionally be brought on purpose, such as when voltage-sensing crowbar circuit protectors are being installed.
An electrical connection that requires two nodes to have the same voltage is known as a short circuit in circuit analysis. Since there is no resistance and hence no voltage drop across the link in a "perfect" short circuit, there is no short circuit.
