A sample of iron receives 50.J of heat energy that raises the temperature of the iron

tatiyna

Answer: 0.02kg

Explanation:

The quantity of heat energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = 50 joules

Mass of iron sample = ? (let unknown value be Z)

C = 100 J/kg°C

Φ = 25°C

Then, Q = MCΦ

50J = Z x 100 J/kg°C x 25°C

50J = 2500J/kg x Z

Z = (50J/2500J/kg)

Z = 0.02kg

Thus, the mass of the iron sample is 0.02kg

The planetary model of the hydrogen atom consists of an electron in a circular orbit about a proton. The motion of the electron

Wittaler [7]

Answer:B=12.52 T

Explanation:

Given

$r=5.30\times 10^{-11} m$

$v=2.2\times 10^{6} m/s$

$q=1.60\times 10^{-19} c$

$Magnetic field(B)=\frac{\nu _0I}{2r}$

$B=\frac{\mu _0Q}{2r\times \frac{2\pi r}{v}}$

$B=\frac{4\pi \times 10^{-7}\times 1.6\times 10^{-19}}{2\times 5.30\times 10^{-11}\times 15.138\times 10^{-17}}$

B=12.52 T

A student sects a leaf of length 7.2 cm to draw. Her drawing is 28.8 cm in length. What is the magnification of the drawing?

Alina [70]

Answer:

A) x4

Explanation:

Magnification is equal to image size divided by the actual size, or M = I/A.

The image size is the student's drawing, which is 28.8 cm, and the actual size is 7.2 cm. Divide them, and cancel out the units, and you should get:

28.8 cm/7.2 cm = 4
