Citrus2011 [14]4 years ago

6 0

Answer:

$\huge \boxed{\mathrm{12000 \ J}}$

Explanation:

Work done (J) = Force (N) × Distance (m)

<em>W</em> = 400 × 30

<em>W</em> = 12000

The work done is 12000 J.

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.

A weight lifter is taking creatine supplements to increase the power in his muscles. What is the most likely effect of taking th

USPshnik [31]

Answer:

Creatine reduces dehydration, muscle cramps or injuries.

Weight gain

Explanation:

Creatine supplements helps to increase amount of creatine in the body. Our bodies naturally have around 120 mmol/kg of creatine. By taking Creatine supplements this amount increases to around 140–150 mmol/kg. Creatine's main function is to help the muscles in your body to produce energy.

Some studies suggest that intake of Creatine reduces dehydration, muscle cramps or injuries. There have been numerous case studies which show that intake of Creatine causes weight gain. Numerous case studies have shown that increased level of Creatine in the blood stream does not affect the kidneys, liver and stomach.
