Answer:

The angle of incidence is the angle between this normal and the incident ray; the angle of reflection is the angle between this normal and the reflected ray. According to the law of reflection, the angle of incidence equals the angle of reflection.

Answer:

hope my answer helps

Explanation:

second law of reflection states that the angle of incidence equals to the angle of reflection,

this is the basic relationship,

so the angle of incidence is also equals to angle of reflection

hope this helps, if not please report it so that someone else gets to try it out

please mark it brainliest

A piece of aluminum with a mass of 3.05 g initially at a temperature of 10.8 °C is heated to a temperature of 20.

fgiga [73]

Answer:

25.3J

Explanation:

Given parameters:

Mass of aluminum = 3.05g

Initial temperature = 10.8 °C

Final temperature = 20 °C

Specific heat = 0.9J/g °C

Unknown:

Amount of heat needed for the temperature to change = ?

Solution:

To solve this problem, we use the expression:

H = m C Ф

H is the amount of heat

m is the mass

C is the specific heat capacity

Ф is the change in temperature

H = 3.05 x 0.901 x (20 - 10.8) = 25.3J

Two capacitors, C1 and C2, give an equivalent capacitance of 9.0 pF when connected in parallel and an equivalent capacitance of

Lilit [14]

Answer:

C₁ = 3 pF

C₂ = 6 pF

Explanation:

Let the capacitance be C₁ and C₂.

For parallel combination

C₁ +C₂ = 9

For series combination

$2=\frac{C_1\times C_2}{C_1+C_2}$

$2=\frac{C_1\times C_2}{9}$

C₁ X C₂ = 18

( 9-C₂ )X C₂ = 18

C₂²- 9C₂ +18 = 0

C₂ = 6 or 3.

C₁ = 3 or 6.

C₁ = 3 pF

C₂ = 6 pF

An experimenter using a gas thermometer found the pressure at the triple point of water (0.01°C) to be 4.80 × 10⁴ Pa and the pre

irakobra [83]

Answer:

$T = -282.33^o C$

Explanation:

As we know that the relation between temperature and pressure is a linear relation

so we have

$P - P_o = \frac{P_1 - P_o}{T_1 - T_o} (T - T_o)$

here we know that

$P_1 = 6.50 \times 10^4$

$P_o = 4.80 \times 10^4$

$T_1 = 100^o C$

$T_o = 0.01^o C$

now we will have

$P - 4.80 \times 10^4 = \frac{(6.50 - 4.80)\times 10^4}{100 - 0.01}(T - 0.01)$

$P = 4.80 \times 10^4 + 170.02(T - 0.01)$

now if P = 0

then we will have

$0 = 4.80 \times 10^4 + 170.02(T - 0.01)$

$T = -282.33^o C$

A helicopter is lifting two crates simultaneously. One crate with a mass of 160 kg is attached to the helicopter by cable A. The

motikmotik

Answer

given,

mass of crate attached by cable A = 160 Kg

mass of crate attached by cable B = 73 Kg

acceleration of helicopter = 1.4 m/s²

tension in the cable when the move up

F = m (a + g)

tension in cable B

F = 73 x (1.4 + 9.8)

F = 73 x 11.2

F = 817.6 N

tension in cable A

F = (160 + 73 ) x (1.4 + 9.8)

F = 233 x 11.2

F = 2609.6 N
