Answer
Explanation:
so the velocity is 39 feet per sec so the impact is 720 cm from the ground
take 720 * 39 sq
Answer:
b. Discharging; anode; cathode
Explanation:
When discharging , it means the battery is producing a flow electric current, the lithium ions are released from the anode to the cathode which generates the flow of electrons from one side to another. When charging Lithium ions are released by the cathode and received by the anode.
Answer:
True strain = 3.7704
Explanation:
Strain is the measure an object that is stretched or deformed. This occurs when a force is applied to an object. Strain deals mostly with the change in length of the object. Strain = Δ L /L = Change in Length over the original Length:
Volume Constancy :
ΔL/L0=A0/ΔA=(D0/ ΔD)=(25mm/0.75mm)^2
ΔL/L0=44.4
Engineering strain:
Engineering strain =ΔL-L0/L0=ΔL/L0-1
Engineering strain =44.4-1=43.4
True strain, ε=In(ΔL/L0)=In(43.4)=3.7704
Note that strain has no unit, so the True strain = 3.7704
