Answer:

$ 30

Explanation:

The tank has a total capacity of 12 gallons

The price for a single gallon is $2.50

Calculating the total for 12 gallons: 12 x 2.50 = $ 30

Therefore, filling the tank with 12 gallons costs $ 30.

Answer:

$ 18.75

Explanation:

Given:

Dave's car has a capacity of 12 gallons.

If the tank is at 3/8 full prior to filling:

The cost of gasoline per gallon is $2.50.

The volume Dave needs to fill:

=1 - \dfrac{3}{8}

=\dfrac{5}{8} of full tank

=\dfrac{5}{8}\times 12

Dave must fill 7.5 gallons.

Total amount Dave will pay:

7.5 gallons x $2.50 =

$ 18.75

Thus, Dave will spend $ 18.75 to completely fill the tank.

Maru [3345]
The response is 176 minutes. The translation of 456 g equals 0.456 kg. The specific heat of ice is 2093 J kg⁻¹, used to calculate heat required for a 25-degree rise, determined by mass multiplied by specific heat and temperature increase. The necessary calculations yield a total heat load of 176164 J. Finally, by dividing heat required by heat supply rate, we ascertain that it will take approximately 176.16 minutes.

Two friends, Burt and Ernie, are standing at opposite ends of a uniform log that is floating in a lake. The log is 3.2m long and
Softa [3030]

Answer:

x = 0.29 m

Explanation:

It is known that the total external force acting on the mass system equals ZERO,

so the center of mass of the entire system will stay stationary.

We find that

m_1\Delta x_1 + m_2\Delta x_2 + m_3\Delta x_3 = 0

Since Ernie approaches Burt's position, we have:

33 x + 290 x + 32(-3.2 + x) = 0

355 x = 102.4

therefore, we conclude that

x = \frac{102.4}{355}

x = 0.29 m

For a short time the position of a roller-coaster car along its path is defined by the equations r=25 m, θ=(0.3t) rad, and z=(−8
ValentinkaMS [3465]

Answer:

Velocity = v = 2.24 m/s

Acceleration = a = 0.20 m/s²

Explanation:

Refer to the attachment below.

Given

z=(−8 cosθ) and θ = 0.3t

z = -8Cos (0.3t)

V = dz/dt

a = v²/R.

Please see full solution below.

A large insulating sheet has a surface charge density σ. what is the electric field strength near the insulating sheet?
Ostrovityanka [3204]
The only scenarios where one can derive dependable data from a noncontact measurement of an insulator's charge state are with free insulative sheets or those that have a grounded conductor backing. In each of these instances, the electric field generated by the charge plays a crucial role.
