Answer:

The correct option is;

The jurors do not all agree on what the decision should be

Explanation:

A hung jury is a jury that are unable to reach an agreement on a verdict following a long consideration and debate and cannot come to the consensus requirement or a supermajority required for conviction and cannot reach a verdict.

A hung jury is possible in the common law legal system that have jurors who render verdict.

Can a heat engine operating with only one thermal reservoir?

Harlamova29_29 [7]

Answer:

Explanation:

Heat engine is a device which operates between two thermal reservoir.One thermal reservoir supply the thermal energy to the heat engine and another thermal reservoir absorb heat rejected by heat engine.These thermal reservoir are infinite amount of heat capacity system.Temperature of thermal reservoir remain constant always.

So we can say that heat engine can not operate by using only one thermal reservoir.

The lead of the threaded shaft of the C-clamp is 0.05 in., and the mean radius of the thread is r = 0.15 in. Assume mus = 0.18.

barxatty [35]

The omitted part of the question shown in bold format

The lead of the threaded shaft of the C-clamp is 0.05 in., and the mean radius of the thread is r = 0.15 in. Assume μs = 0.18 and μk = 0.16. What couple must be applied to the shaft to exert a 30-lb force on the clamped object?

Answer:

C = 0.967 in. lb

Explanation:

Given that:

The lead of the threaded shaft of the C-clamp is 0.05 in.

∴ the pitch of the screw = 0.05 in

the mean radius of the thread is r = 0.15 in.

Assuming:

(μs)= 0.18 which implies the coefficient of the static friction

(μk) = 0.16 (coefficient of kinetic friction)

Force = 30-lb

What couple must be applied to the shaft to exert a 30-lb force on the clamped object?

To determine the Couple (C) that must be applied; we use the expression:

C = Fr tan ( $\theta_k$ + $\alpha$ )

where; F = force

r = mean radius

$\theta_k$ = angle of kinetic friction

$\alpha$ = pitch angle

NOW, let's take then one after the other.

From the coefficient of the static friction and the kinetic friction; we can solve for their respective angles, so we have:

Angle of static friction ( $\theta_s$ ) $= tan^{-1}(U_s)$

( $\theta_s$ ) = $tan^{-1}(0.18)$

( $\theta_s$ ) = 10.204°

Angle of kinetic friction ( $\theta_k$ ) $= tan^{-1}(U_k)$

$\theta_k$ $= tan^{-1}(0.16)$

$\theta_k$ = 9.0903°

To determine the pitch angle( $\alpha$ ); we apply the expression:

( $\alpha$ ) = $tan^{-1}(\frac{p}{2 \pi r} )$

( $\alpha$ ) = $tan^{-1}(\frac{0.05}{2 \pi 0.15} )$

( $\alpha$ ) = $tan^{-1}(0.0530516 )$

( $\alpha$ ) = 3.0368°

Have gotten our parameters to solve for Couple (C); then we have:

C = Fr tan ( $\theta_k$ + $\alpha$ )

substituting our values; we have:

C = (30 × 0.15) tan ( 9.0903 + 3.0368)

C = 4.5 × tan ( 12.1271)

C = 4.5 × 0.2148761968

C = 0.96669428854 in.lb

C = 0.967 in. lb

Therefore, 0.967 in. lb couple must be applied to the shaft to exert a 30-lb force on the clamped object.

You insert a dielectric into an air-filled capacitor. How does this affect the energy stored in the capacitor?.

kherson [118]

The effect that the energy stored in the capacitor is that option b: Energy stored in the capacitor will decrease.

<h3>How does electric field affects the energy stored in a capacitor that contains a dielectric?</h3>

If a dielectric is said to be inserted into any kind of an isolated and charged capacitor, the stored energy is known to often decreases to about 33% of its real value.

The capacitance of a give group of charged parallel plates is known to often increased by the inputting of a dielectric material. The capacitance is known to be inversely proportional to the electric field that tends to exist between the plates, and thus, the presence of the any form of dielectric tend to lower the effective electric field.

Therefore, The effect that the energy stored in the capacitor is that option b: Energy stored in the capacitor will decrease.
