A 36,287 kg truck has a momentum of 907,175 kg • m/s. What is the trucks velocity.
Airida [17]

Momentum = Mass x Velocity

Put the values where they belong and solve for Velocity.

In this case, since Mass is being multiplied by Velocity, to solve for be Velocity you would divide both sides by Velocity.  The velocity will equal the momentum divided by the mass.

What is the magnetic field strength at point 1 in the figure? (figure 1)
Lana71 [14]

The magnetic field strength at point 1 in the figure will be 6.67 ×10⁻⁵ T.

<h3>What is magnetic field strength?</h3>

The number of magnetic flux lines on a unit area passing perpendicular to the given line direction is known as induced magnetic field strength .it is denoted by B.

The magnetic field strength is found as;

B = \frac{\mu_0I}{2r}  \\\\ \mu_0 = 4 \PI \times 10^{-7}

In the formula,I denote current, and r denotes the distance between the point and the current carrying wire and magnetic field due to current in the bottom wire.

At point 1, the net magnetic field is found as the sum of magnetic field due to current in the top wire.

\rm B_{net} = B1_+(-B_2)

B = \frac{ 4 \PI \times 10^{-7}I}{2r}  \\\\  \rm B_{net} = B_1_+(-B_2)\\\\ \rm B_{net} = \frac{4 \times \pi \times 10^{-7} \times 10}{2 \times \pi \times 0.02} -\frac{4 \times \pi \times 10^{-7} \times 10 }{2 \times \pi \times 0.06} \\\\\  \rm B_{net} = 6.67 \times 10^{-5} T

Hence, the magnetic field strength at point 1 in the figure will be 6.67 ×10⁻⁵ T.

What is the equivalent resistance?​
mote1985 [20]

Answer:

C 3.33 Ω

Explanation:

From the equation given    1 / Rtot = 1/10 + 1/5 =  3/10

 then Rtot = 10/3 = 3.33 Ω

As an aside:

When there are only two resistors in parallel, the equivalent R is

=    R1*R2 / (R1 + R2) =  10*5 / (10+5) = 50 / 15 = 3.33 Ω
