A birds shadow is larger the higher it flies and I think when it is directly in sunshine and not shy of it

Answer:

Hope it helps

Explanation:

The higher the bird flies, the bigger the shadow it casts, however, for the shadow to be visible enough the plane or bird would have to be close to the line directly from the sun.

Q|C A sinusoidal wave in a string is described by the wave function

creativ13 [48]

The maximum transverse force on a 1.00cm segment of the string is 0.045N.

The maximum transverse force on the segment,

l=1.00cm=1.00cm×1m/100cm=0.01m is,

F=μla

=(12.0×10^−3kg/m)×(0.01m)×(375m/s^2)

=0.045N

Hence the maximum force is 0.045N

The battery has a voltage of 12V. R1 = R2 = 100Ω.

Margaret [11]

Answer:

<h3> FOR PARALLEL CONNECTION</h3><h3>I1 = 0.12A</h3><h3>I2 = 0.12A </h3><h3>IT =0.24A</h3><h3>FOR SERIES CONNECTION</h3><h3>I1 = I2 = 0.06A</h3><h3>IT =0.06A</h3><h3 />

Explanation:

According to ohms law, V =ITRt

V is the supply voltage

IT is the total current flowing in the circuit

Rt is the total equivalent resistance

Given R1= R2= 100Ω

V= 12V

FOR PARALLEL CONNECTION;

To calculate the total current IT in the battery, we need to calculate the total equivalent resistance RT first. For a parallel connected circuit, the equivalent resistance in the circuit is the sum of the reciprocal of its individual resistances as shown;

$\frac{1}{RT} = \frac{1}{100} + \frac{1}{100}\\\frac{1}{RT} = \frac{2}{100} \\\frac{RT}{1} = \frac{100}{2}\\$

RT = 50Ω

from the equation above;

IT = V/RT

IT = 12/50

IT = 0.24A

Note that in a parallel connected circuit, different current flows through the resistances but the same voltage is across them.

IT = I1+I2

For current in resistance R1;

I1 = V/R1

I1 = 12/100

I1 = 0.12A

Since both resitance are the same, they will share the total current equally. Therefore I2 = 0.12A

FOR SERIES CONNECTION;

The total equivalent resistance in the circuit will be the sum of their individual resistances.

$RT = R1+ R2$

RT = 100Ω+100Ω

RT = 200Ω

IT = V/RT

IT = 12/200

IT = 0.06A

Since the resistances are connected in series, the same current will flow through them but different voltages. The total current flowing in the circuit will be the same current flowing through the resistors.

Therefore I1 = I2 = 0.06A

The vector quantity that defines the distance and direction between two positions. It is a change in your position.

pantera1 [17]

Answer:

<u><em>Displacement</em></u>

Explanation:

To describe the<em> change in position</em> you need to indicate the distance between the final and initial positions and the direction in which you moved. The distance is the magnitude.

The quantities that need both magnitude and direction to be described are named <em>vector quantities</em> or, just, vectors.

<em>The vector quantity that defines both the distance and direction between two positions </em>describes the <em>change in your position</em> and is named displacement. For instance, to indicate how you can goe to the supermarket from your house you cannot just say walk 2 miles. You need to indicate the direction; let's say 2 miles North. In this case, the displacement when you goe from your house to the supermarket is 2 miles North. And it is different of the displacement when you comeback from the supermarket to your house, because it would be 2 miles South.
