Answer:

Radio Waves

Explanation:

Answer:

The equivalent resistance of the combination is R/100

Explanation:

Electric Resistance

The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.

Parallel connection of resistances: If R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:

[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+...+\frac{1}{R_n}[/tex]

If we have 10 wires of resistance R/10 each and connect them in parallel, the equivalent resistance is:

[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R/10}+\frac{1}{R/10}+\frac{1}{R/10}...+\frac{1}{R/10}[/tex]

This sum is repeated 10 times. Operating each term:

[tex]\displaystyle \frac{1}{R_e}=\frac{10}{R}+\frac{10}{R}+\frac{10}{R}+...+\frac{10}{R}[/tex]

All the terms have the same denominator, thus:

[tex]\displaystyle \frac{1}{R_e}=10\frac{10}{R}=\frac{100}{R}[/tex]

Taking the reciprocals:

[tex]R_e=R/100[/tex]

The equivalent resistance of the combination is R/100

Answer:

15,000 m

Explanation:

[tex]speed = \frac{distance}{time} [/tex]

speed = 50 m/s

time = 5 minutes × 60

= 300 seconds

substitute the values into the formula

[tex]50 = \frac{distance}{300} [/tex]

[tex]50 \times 300 = distance[/tex]

[tex]15000 \: m = distance[/tex]

[tex]distance = 15000 \: m[/tex]

Yes.

Explanation:

Yes, we emphasize performance over participation of kids in a competition which causes negative effect on kid's personality. We also prefer those children whose families can afford the fees which is our big failure. We should  emphasize participation over performance and prefer those child who has the ability to win the game instead of those who can afford the fees.

Answer:

A. 2.2 ɥC

Explanation:

Given;

electric field strength, E = 1236 N/C

distance of the source charge, r = 4 m

Electric field strength is calculated as;

[tex]E = \frac{kQ}{r^2}[/tex]

where;

Q is the magnitude of the source charge

k is Coulomb's constant = 9 x 10⁹ Nm²/C²

[tex]E = \frac{kQ}{r^2} \\\\kQ = Er^2\\\\Q = \frac{Er^2}{k} \\\\Q = \frac{(1236)(4^2)}{9 \ \times \ 10^9} \\\\Q = 2.197 \ \times \ 10^{-6} \ C\\\\Q = 2.197 \ \mu \ C[/tex]

Therefore, the correct option is A. 2.2 ɥC

Answer:

118.3 J

Explanation:

Givens:

m = 1.4 kg

V = 13 m/s

Formula for kinetic energy:

KE = (1/2)*(m)*(v)^2

KE = .5*(1.4 kg)*(13 m/s)^2

KE 118.3 J

J = Joules

Answer:

209000 kg*m/s

Explanation:

Momentum is caclucated using the equation P=mv. Where m is mass and v is velocity.

If you are required to show your work it would be the following:

1400*70=98000 kg*m/s

1300*85=110500 kg*m/s

98000+110500=208500 kg*m/s

209000 kg*m/s

Answer:

Radioactive Dating

Explanation:

To get the age range of rocks or fossils, researchers usually make use of radiometric dating technique which is also called radioactive dating. Now, this radioactive dating is based on the principle of comparison between the abundance that's observed from a naturally occurring radioactive isotope including its decay products, with the use of known decay rates.

Answer: You didnt finish the question. But as magma cools it turns to igneous rock.

Answer:

Explained below

Explanation:

When we eat food, our body gets chemical energy from it. Now, this chemical energy from the food is changed into some different energy forms that is useful to it. They include:

-Chemical to mechanical energy to aid in movement of muscles

- chemical to thermal energy to aid in regulating the body temperature.

- chemical to electrical energy to aid the brain in thinking.

Thus is similar to how a machine converts energy because machines also generate energy after being powered and convert to other forms of energy. For example, an alarm clock converts electrical energy to sound energy, hair dryer converts electrical energy to thermal/heat energy.

Answer:The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω): V (V) = I (A) × R (Ω) The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): P (W) = V (V) × I (A) AC Ohm's law calculator.

Explanation:

40 ampere current passes through a 1 kW heater with 25 Voltage across it.

The difference in electric potential between two places is known as voltage, often referred to as electric pressure, electric tension, or potential difference. It relates to the amount of labor required to transfer a test charge between two places in a static electric field.

Given that power of the source is 1 kW and voltage is 25 V

current is given as,

Power = Voltage*Current

1kW = 25*Current

Current = 1000/25 = 40 ampere.

40 ampere current passes through a 1 kW heater with 25 Voltage across it.

Given that,

Mass, m = 250 g

Volume of the container, V = 50 cm³

To find,

The density of the oil.

Solution,

Density = mass/ volume

The computation for density is as follows :

[tex]\rho =\dfrac{m}{V}\\\\\rho =\dfrac{250\ g}{50\ cm^3}\\\\=5\ g/cm^3[/tex]

So, the density of the oil is [tex]5\ g/cm^3[/tex].

Answer:

Hiiiiiiii........where r u frm??

Answer:

Following are the solution to this question:

Explanation:

In this question, some of the information is missing that's why its solution can be defined as follows:

[tex]v= 0\\\\u= 1.0 \frac{m}{s} \\\\s= 1\\\\m= 54 \ kg\\[/tex]

Using formula:

[tex]\to v^2-u^2=2\cdot a\cdot s \\\\\to 0^2 - 1.0^2= 2 \cdot a \cdot 1\\\\\to - 1=2a\\\\\to a= -\frac{1}{2} \ \frac{m}{s^2}\\\\ \to \bold{F= m\cdot a}\\\\[/tex]

[tex]=54 \times - \frac{1}{2}\\\\= -27\ N[/tex]

Answer:

[tex]F=1.06\times 10^{-18}\ N[/tex]

Explanation:

Given that,

Mass of the Moon, [tex]M=7.34\times 10^2\ kg[/tex]

Mass of the person, m = 66 kg

The radius of Moon, [tex]r=1.74\times 10^6\ m[/tex]

We need to find the force between the person and the Moon. The formula for the gravitational force is given by :

[tex]F=G\dfrac{Mm}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{7.34\times 10^2\times 66}{(1.74\times 10^6)^2}\\\\=1.06\times 10^{-18}\ N[/tex]

So, the required force is [tex]1.06\times 10^{-18}\ N[/tex].

Answer:

1626.4 N

Explanation:

Given that a 82 kg man, at rest, drops from a diving board 3.0 m above the surface of the water and comes to rest 0.55 s after reaching the water. What force does the water exert on him?

The parameters to be considered are:

Distance S = 3m

Time t = 0.55s

Since the man started from rest, initial velocity u = 0

Using second equation of motion

S = Ut + 1/2at^2

3 = 1/2 × a × 0.55^2

3 = 1/2 × a × 0.3025

a = 3/ 0.15125

a = 19.83 m/s^2

Force = mass × acceleration

Force = 82 × 19.83

Force = 1626.4 N

Therefore, the force that water exerted on him is 1626.4 N
