sveta [45]3 years ago
8 0

Answer:

80 amperes

Explanation:

Current in the circuit = ?

Voltage in the circuit = 160 Volts

Resistance = 2 Ω

Voltage = Current x Resistance

V = IR

160V = I x 2 Ω

I = 160V / 2 Ω

I = 80 Amperes

Therefore the current in the circuit is 80 amperes :)

Explain why the gravitational acceleration of any object near earth is the same matter what was the mass of the object
Gre4nikov [31]
It takes greater force to accelerate an object that has more mass. But the gravitational force between the Earth and an object is greater when the object hass more mass. It works out just right to make any object with any mass accelerate at the same rate.

Two sources of light of wavelength 720 nm are 10 m away from a pinhole of diameter 1.2 mm. How far apart must the sources be for
julia-pushkina [17]

Answer:

The value is  y  =  0.00732 \ m    

Explanation:

From the question we are told that

    The wavelength of each source is  \lambda  = 720 \ nm =  720 *10^{-9} \  m

     The distance from the pinhole D = 10 \ m

     The diameter is d =  1.2 mm = \frac{1.2}{1000} = 0.0012 \ m

Generally from Rayleigh's criterion  we have that the distance between the sources of light for their diffraction patterns is mathematically represented as '

        y  =  \frac{ 1.22 *  \lambda *  D}{d}

=>      y  =  \frac{ 1.22 * 720 *10^{-9}*   10 }{ 0.0012}

=>      y  =  0.00732 \ m

A Martian leaves Mars in a spaceship that is heading to Venus. On the way, the spaceship passes earth with a speed v = 0.80c rel
hjlf

To find the relative distance from one point to another it is necessary to apply the Relativity equations.

Under the concept of relativity the distance measured from a spatial object is given by the equation

l = l_0 \sqrt{1-\frac{v^2}{c^2}}

Where

l_0= Relative length

v = Velocity of the spaceship

c = Speed of light

Replacing with our values we have that

l = l_0 \sqrt{1-\frac{v^2}{c^2}}

l = 1.2*10^{11} \sqrt{1-\frac{0.8c^2}{c^2}}

l = 1.2*10^{11} \sqrt{1-0.8^2}

l = 7.2*10^{10}m

Therefore the distance between Mars and Venus measured by the Martin is 7.2*10^{10}m
