That's the "centripetal" force.  It produces the centripetal acceleration
that pulls the object away from a straight path into a bent path.

A 0.676 m long section of cable carrying current to a car starter motor makes an angle of 57.7º with the Earth’s 5.29 x 10^−5T f
Studentka2010 [4]

Answer:

The current in the wire under the influence of the force is 216.033 A

Solution:

According to the question:

Length of the wire, l = 0.676 m

\theta = 57.7^{\circ}

Magnetic field of the Earth, B_{E} = 5.29\times 10^{- 5} T

Forces experienced by the wire, F_{m} = 6.53\times 10^{-3} N

Also, we know that the force in a magnetic field is given by:

F_{m} = IB_{E}lsin\theta

I = \frac{F_{m}}{B_{E}lsin\theta}

I = \frac{6.53\times 10^{-3}}{5.29\times 10^{- 5}\times 0.676sin57.7^{\circ}

I = 216.033 A

What are the units used to measure specific heat capacity?.
Nuetrik [128]

The units used to measure specific heat capacity is Joules per kilogram per Kelvin.

<h3>What is specific heat capacity?</h3>

It is the amount of heat absorbed per kilogram of material when the temperature rises by 1 kelvin.

Specific heat capacity C is the Joules of energy in form of heat per kilogram per Kelvin temperature. The units represented by

C = ___ J/kg.K

Thus, the units used to measure specific heat capacity is Joules per kilogram per Kelvin.

An irregularly shaped stone was lowered into a graduated cylinder holding a volume of water equal to 20L. The height of water ro
vagabundo [1.1K]

Answer:

2.45 g/mL

Explanation:

(assuming that the original volume was 20 mL and not L)

Since you know the amount of water in the cylinder before and after you placed the rock in, you can subtract them to get the volume of the rock itself. 30.2-20=10.2 mL.

To get the rock's density, use the equation d=\frac{m}{v}, where m is mass and v is volume.

d=\frac{25 g}{10.2mL}\\\\d=2.45 g/mL

Umnica [9.8K]
The answer to this is 1 kg.
You use this equation:
m2 = m1 (g - a) / [a + g u cos θ + g sin θ]

You plug in the given values:
m2 = 0.7 (9.81 - 0.2) / [0.2 + 9.81(0.20) cos 30 + 9.81 sin 30)

The result is
m2 = 1 kg

Power is the rate of doing work, P = W/t. As is implied by the equation for power, a unit of power <span>is equivalent to a unit of work divided by a unit of time. We calculate as follows:

P = W/t = Fd/t where d/t = v
P = Fv = 110(80)
power is 8800 watts</span>
