You start by writing down your parameters;
u=60m/s
v=0
t=8s
So acceleration(a)=v-u/t
=0-60/8
=-60/8
=-7.5m/s
To the nearest hundredth will be
-7.5*100
=-750m/s
Answer:
Do = density of obect Dw = density of water
Weight of object = V g Do
Weight of water = V g Dw
F = m a = V Do a = V g Do - V g Dw
Acceleration of object = mass * force on object
Do (g - a) = Dw g
Do = Dw ( 1 / (1 - a / g) = 1000 * 1 / (1 - 3.75 / 9.80) kg/m^3
Do = 1441 kg / m^3
If no acceleration then density of object = density of water
45° × π/180 = 0,7854 rad
ω = θ /t
ω = 0.7854 / 0.75 = 1.0472 rad/s
Explanation:
This process is called Bonding and it is done to provide low resistance path to ground.
"Bonding — a low impedance direction achieved by permanently connecting all non-current-carrying metal parts to maintain electrical stability and to be able to conduct any current that is likely to be put on it safely.
The answer is c C is the correct answer
