Answer:

0.00185 °C

Explanation:

From the question,

The potential energy of the bird = heat gained by the water in the fish tank.

mgh = cm'(Δt)................... Equation 1

Where m = mass of the bird, g = acceleration due to gravity, h = height, c = specific heat capacity of water, m' = mass of water, Δt = rise in temperature of water.

make Δt the subject of the equation

Δt = mgh/cm'............... Equation 2

Given: m = 1 kg, h = 40 m, m' = 50.5 kg

constant: g = 9.8 m/s², c = 4200 J/kg.K

Substitute into equation 2

Δt = 1(40)(9.8)/(50.5×4200)

Δt = 392/212100

Δt = 0.00185 °C

What is the number of significant digits in the measurement 104.100 m?
Oksana_A [137]

Answer:

6

6 significant digits

Explanation:

Number of significant digits of a number are the number of digits that carry a relevant contribution to the measurement.

For the case above;

104.100

rule - all digits to the right of the decimal of any number equal or greater than 1 will count as a significant digit.

104.100 --- .100 ( the three digits counts)

And since the the digits to the left are none zero digits, so they all count as significant digits.

104.100 --- 104 ( the three digits counts)

The total number of significant digits,

Since all the digits of the number 104.100 will count as a significant digit.

The number of significant digits is equal to the number of digits in the number.

N = 6

6 significant digits
