A force of 25 newtons moves a box a distance of 4 meters in 5 seconds.

Simora [160]

By definition, we have that the work done is given by:

$W = F * d$

Where,

F: force in the direction of displacement

d: displaced distance

Substituting values we have:

$W = (25) * (4)\\W = 100 Nm$

Then, the power is given by:

$P = \frac{W}{t}$

Where,

t: time

Substituting values we have:

$P = \frac{100}{5}$

$P = 20\frac{Nm}{s}$

Answer:

The work done on the box is 100 Nm, and the power is 20 Nm/s.

Dust particles in air have a typical mass of 5.0 x 10-16 kg. They undergo irregular motion due to collisions with air molecules.

Mars2501 [29]

Answer:

Rms speed of the particle will be $38.68\times 10^8m/sec$

Explanation:

We have given mass of the air particle $m=5\times 10^{-16}kg$

Gas constant R = 8.314 J/mol-K

Temperature is given T = $27^{\circ}C=273+27=300K$

We have to find the root mean square speed of the particle

Which is given by $v_{rms}=\sqrt{\frac{3RT}{m}}=\sqrt{\frac{3\times 8.314\times 300}{5\times 10^{-16}}}=38.68\times 10^8m/sec$

So rms speed of the particle will be $38.68\times 10^8m/sec$

A 0.0414 kg ingot of metal is heated to 243◦C

tino4ka555 [31]

Answer:

448 J/kg/°C

Explanation:

m₁ C₁ (T₁ − T) + m₂ C₂ (T₂ − T) = 0

(0.0414 kg) C (243°C − 20.4°C) + (0.411 kg) (4186 J/kg/°C) (18°C − 20.4°C) = 0

(9.22 kg°C) C − 4129 J = 0

C = 448 J/kg/°C
