The entire universe would be destroyed. The earth wouldn't be affectedly it until 9 minutes after the explosion
Answer:
0.00321 Nm
Explanation:
= Final angular velocity = 3.5 rad/s
= Initial angular velocity = 0
= Angular acceleration
= Angle of rotation = 2 rev
Equation of rotational motion
Moment of inertia is given by
Torque is given by
The torque required is 0.00321 Nm
Answer:
(0.25X+25)N
Explanation:
-let the weight of the box be X.
-Given that the the force needed is equal to one half the weight of the box plus 25N:
Hence, the total force needed is (0.25X+25)N
Answer:
The formula for calculating Density is:
= Mass / Volume
From this formula, we can say that the relationship between Mass and Density is a direct one. In other words, if mass is increasing - all else being equal - then density will increase as well.
If mass however was decreasing, density would have to decrease as well.
For example, assume 3 bricks have masses of 5kg, 10kg and 15kg. Also assume that the bricks all have the same volume of 5 m³.
Density of 5kg brick = 5 / 5 = 1 kg/m³
Density of 10kg brick = 10 / 5 = 2kg / m³
Density of 15kg brick = 15 / 5 = 3 kg /m³
<em>Notice how density increases as mass increases and decreases when mass decreases. </em>
The electric field is given by volts/distance:
. The breakdown voltage of dry air is about 3x10^6V/m. So solving for V we get
