There is often confusion between weather and climate. Weather is the condition of the atmosphere at a particular place over a short period of time.

Answer:

F = F2 - F1     where F is the net force upwards

F = 5 - (.5 * 9.8) = (5 - 4.9) N = .1 N

The magnitude of the electric field inside the conductor will be 0.208 N/C.

An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.

Given data;

length of rod = 25 cm = 0.25 m

Potential Difference = 52 mV = 0.052 Volts

The electric field is found as the ratio of the potential difference and the length;

[tex]\rm E =\frac{0.052}{0.25} \\\\ E=0.208 \ N/C[/tex]

Hence,the magnitude of the electric field inside the conductor will be 0.208 N/C.

Its PO

Explanation:

I got it right on Edge.

Given the total energy in the wire, current and time elapsed, the potential difference is 50 Volts.

The electric power is expressed as P = VI.

Where V is the potential difference, I is the electric current and P is the electric power.

Also, the consumption of energy per unit of time is called power. It is expressed as P = E / t

Given that;

First, we determine the power.

P = E / t

P = 500J / 5s

Power = 100W

Next, we determine the potential difference.

P = V × I

V = P / I

V = 100W / 2.00A

V = 50V

Given the total energy in the wire, current and time elapsed, the potential difference is 50 Volts.

The Potential difference is 50 Volts.

The potential difference is a measure of the energy given to the charge carriers in a circuit

We know that  the electric power is expressed as P = VI.

V is the potential difference

I is the electric current
P is the electric power.

Also we know that power is expressed as P = E / t

Given

Current( I) = 2.00A ,time t = 5s

Total energy E = 500J

To find the power

P = E / t  = 500J / 5s = 100W

Now , To find the potential difference.

P = V × I (By rearranging it)

V = P / I

V = 100W / 2.00A = 50 V

Therefore , the total energy in the wire, current and time elapsed, the potential difference is 50 V.

The decay constant for radium-226 is larger than the decay constant for carbon-14 due to its obtained value.

The reduction in the number of radionuclides per unit time is the rate of decay.

The decay constant of the radium-226 is;

[tex]\lambda_1=\frac{ 16}{100}\times 266 \\\\ \lambda_1= -36.16[/tex]

The decay constant of the carbon-14 is;

[tex]\lambda_2=\frac{ -57.3}{100}\times 14 \\\\ \lambda_1= -802.2[/tex]

Hence, the decay constant for radium-226 is larger than the decay constant for carbon-14.

Answer:

  0.693/1600 > 0.693/5730

Explanation:

The decay constant is the reciprocal of the time it takes for the radioactivity to decline to about 36.8% of its original value. It is the value of k in the multiplier e^(-kt), which tells the fraction remaining after time t.

When compared to the half-life, h, the value of k is ...

  k = 0.693/h . . . . . decay constant for half-life h

Effectively, the decay constant is proportional to the inverse of the half-life. The constant of proportionality is ln(2) ≈ 0.693.

__

decay constant for radium-226:

  0.693/1600 ≈ 4.33×10^-4

decay constant for carbon-14:

  0.693/5730 ≈ 1.21×10^-4

Since 4.33×10^-4 is greater than 1.21×10^-4, the decay constant of radium-226 is larger than that of carbon-14.

_____

Additional comment

Taking the reciprocal of a positive number reverses the ordering:

  1600 < 5730

  1/1600 > 1/5730

The half-life of radium-226 is less than that of carbon-14, so its decay constant will be larger.

Explanation:

The minimum amount of water needed for bathing assuming the water begins at room temperature is 16.58kg.

When two bodies at different temperature come into contact, they share the heat through conduction. After some time, temperature of both becomes equal. This condition is said to be a body in thermal equilibrium with other.

Heat gained by the water = heat lost by the ill person

m x Cw x ΔT = M x Cp x Δt

where, mass of person M = 80kg, Cp =specific heat of body =3470, specific heat of water Cw= 4186, then mass of water m will be

m x 4186 x (37-25) =- 80 x 3470 x (37-40)

m = 16.58kg

Thus, the mass of water needed is 16.58kg.
