Answer:
a) Current = 11 mA
b) Energy = 66 mJ
c) Power = 101.54 W
Explanation:
a) Voltage, V = IR
Voltage, V = 6 V, Resistance, R = 550 Ω
Current, I 
b) Energy = Current x Voltage = 6 x 0.011 = 0.066 J = 66 mJ
c) 
Answer:
Explanation:The elements that can form basic compounds are;
Rubidium
Arsenic
Silicon
Antimony
Rubidium, Arsenic, Silicon, Antimony are the substances that can for the basic compounds. I think sulfur also play its role somehow in formation of basic compounds.
Answer:
acceleration is the answer
<span> Required Volume (V) = Area of the base * Height
Area of the base = Pi [ 3.27² - (2.47/2)² ] since 2.47 is diameter and not radius. = Pi ( 9.981675 )
Therefore Volume (V) = Pi ( 9.981675) * 15.9 = 498.5978739 cm³ = 498.6 cm³.</span>
Answer:
(a) 142.5 rad/s
Explanation:
Torque = 45 Nm
Moment of inertia = 30 kgm^2
w0 = 0, t = 95 second
(a) Let it is rotating with angular speed w.
Torque = moment of inertia x angular acceleration
45 = 30 x α
α = 1.5 rad/s^2
Use first equation of motion for rotational motion
w = w0 + α t
w = 0 + 1.5 x 95
w = 142.5 rad/s
(b) if he hold rocks, then the moment of inertia change and then angular acceleration change and then final angular velocity change.
