DENIUS [597]

Answer:

Both equilibrium price and quantity will increase.

Explanation:

An increase in the income of video game players will surely lead to an upward shift in the supply and demand curve. This shift in the supply and demand curve would affect the equilibrium price and quantity positively leading to a correspondent increase in the equilibrium price and quantity.

A 710 kg car drives at a constant speed of 23 m/s. It is subject to a drag force of 500 N. What power is required from the car's
inn [45]

Explanation:

Given that,

Mass of the car, m = 710 kg

Speed of the car, v = 23 m/s

Drag force, F = 500 N

(a) Let P is the power is required from the car's engine to drive the car on the level ground. Power is given by :

P=F\times v\\\\P=500\ N\times 23\ m/s\\\\P=11500\ W

(b) Let P is the power is required from the car's engine to drive the car on up a hill with a slope of 2 degrees.

At this slope, force will be, F=mg\ \sin\theta

Total force will be :

F=710\times 9.8\times \sin(2)+500\\F=742.83\ N

Power is given by :

P=F\times v\\\\P=742.83\times 23\\\\P=17085.09\ W

or

P = 17 kW

Neurons in our bodies carry weak currents that produce detectable magnetic fields. A technique called magnetoencephalography, or
Stolb23 [73]

Answer:

I = (1.80 × 10⁻¹⁰) A

Explanation:

From Biot Savart's law, the magnetic field formula is given as

B = (μ₀I)/(2πr)

B = magnetic field = (1.0 × 10⁻¹⁵) T

μ₀ = magnetic constant = (4π × 10⁻⁷) H/m

r = 3.6 cm = 0.036 m

(1.0 × 10⁻¹⁵) = (4π × 10⁻⁷ × I)/(2π × 0.036)

4π × 10⁻⁷ × I = 1.0 × 10⁻¹⁵ × 2π × 0.036

I = (1.80 × 10⁻¹⁰) A

Hope this Helps!!!

What obstacles will you need to deal with to build railroad routes
polet [3.4K]

<u>Answer:</u>

<em>Construction of a railroad route is a strenuous task and one has to face several obstacles. </em>

<u>Explanation:</u>

Setting up the best possible plan for laying a rail route is a time-taking task. Several factors like economical nature of the plan, proper availability of building materials, minimum river crossings etc should be considered.

To build a railroad route the government has to get hold of the land through which the railroad route is planned. This is never an easy task. The people of the area have to be given adequate compensation and should be properly evacuated. The chances of people disapproving the plan are more.
