The government should put it support in a combination of sources, as no source in the present can fully provide all energy requirements.

Answer:

I believe that the government should focus on supporting solar and wind energy over anything else.

Explanation:

There are two reasons why I believe the government should put the greatest efforts in solar and wind energy.

First of all, obtaining coal, natural gas, and oil is cheap because the governments and companies have put great amounts of money in research to produce it at the lowest possible costs. Therefore if we fund research with the same model, we are going to obtain cheaper costs. The second reason is that they are renewable and 0 pollution sources of energy, unlike coal, gas, and il. Also, we can create engines like the ones electric cars use, to all transports.

There are other efforts like nitrogen, geothermic energy and my favorites, gravitational rejection impulse energy and electromagnetic energy like the one the Japanese shinkansen uses.

A portable television using a 12 volt, 3 Ah rechargeable battery can operate for a period of about 6 hours. What is the average
bezimeni [28]

Answer:

0.5 A

Explanation:

Current: This is defined as the rate flow of electric charge round a circuit,

The S.I unit of current is Ampere (A). Mathematically,

Current (I) = C/t

I = C/t................  Equation 1

Where  C = capacity of the battery, t = time

Given: C= 3 Ah, t = 6 hours.

Substitute into equation 1

I = 3/6

I = 1/2

I = 0.5 A.

Hence the average current drawn = 0.5 A

A 42.0-cm diameter disk rotates with a constant angular acceleration of 2.70 rad/s2. It starts from rest at t = 0, and a line dr
Zielflug [23.3K]

Answer:

6.21 rad/s

1.3041 m/s, 0.567 m/s²

106.4778\ ^{\circ}

Explanation:

\omega_f = Final angular velocity

\omega_i = Initial angular velocity = 0

\alpha = Angular acceleration = 2.3 rad/s²

\theta = Angle of rotation

t = Time taken = 2.3 s

Equation of rotational motion

\omega_f=\omega_i+\alpha t\\\Rightarrow \omega_f=0+2.7\times 2.3\\\Rightarrow \omega_f=6.21\ rad/s

The angular speed is 6.21 rad/s

Linear velocity is given by

v=r\omega\\\Rightarrow v=0.21\times 6.21\\\Rightarrow v=1.3041\ m/s

Linear velocity is 1.3041 m/s

Tangential acceleration is given by

a_t=r\alpha\\\Rightarrow a_t=0.21\times 2.7\\\Rightarrow a_t=0.567\ m/s^2

Tangential acceleration is 0.567 m/s²

\theta=\omega_it+\dfrac{1}{2}\alpha t^2\\\Rightarrow \theta=0\times t+\dfrac{1}{2}\times 2.7\times 2.3^2\\\Rightarrow \theta=7.1415\ rad

In degress the angle would be

57.3+7.1415\times \dfrac{180}{\pi}=466.47780\ ^{\circ}

From x axis it would be

466.47780-360=106.4778\ ^{\circ}

The angle is 106.4778\ ^{\circ} from x axis

a specimen of oil having an initial volume of 5000cm³ is subjected to a pressure of 10⁴N/m² and the volume decreases by 0.20cm³.
inessss [21]

Answer:

 B = 2.5 10⁸ Pa

Explanation:

The volume modulus is defined by

           B = - \frac{P}{ \frac{\Delta V}{V} }

           

The negative fate is for the module to be positive since the volume change is negative

       

It is not necessary to reduce the volumes to the SI system, since they are both in the same units

             B = - \frac{10^4}{ \frac{-0.20}{5000} } = \frac{10^4}{4 \ 10^{-5} }

             B = 2.5 10⁸ Pa
