An argon gas occupies 56.2 L at 760 torr. If the volume of gas dereases to 1/4 of the original volume ,calculate its final press

Elina [12.6K]

Answer:

3040 torr

Explanation:

Applying,

PV = P'V'..................... Equation 1

Where P = Initial Pressure, V = Initial volume, P' = Final pressure, V' = Final volume.

Make P' the subject of the equation

P' = PV/V'................. Equation 2

From the question,

Given: P = 760 torr, V = 56.2 L, V' = 56.2/4 = 14.05 L

Substitute these values into equation 2

P' = (56.2×760)/14.05

P' = 3040 torr

What is the ﬁnal equilibrium temperature when 12 g of milk at 7◦C is added to 175 g of coﬀee at 69◦C? Assume the speciﬁc heats o

lina2011 [118]

Answer:

ﬁnal equilibrium temperature is 65.02 ◦C

Explanation:

Given data

milk = 12 g

temp milk = 7◦C

coffee = 175 g

coffee temp = 69◦C

to find out

ﬁnal equilibrium temperature

solution

we apply here equilibrium condition i.e m c ΔT

milk mass × c × ΔT = coffee mass × c × ΔT

12 × 1 × (T- 7) = 175 × 1 × ( 69- T)

12T - 84 = 12075 - 175 T

187 T = 12159

T = 65.02

so ﬁnal equilibrium temperature is 65.02 ◦C

A pickup truck has a width of 79.0 in. If it is traveling north at 42 m/s through a magnetic field with vertical component of

bekas [8.4K]

Answer:

The magnitude of the induced Emf is $0.003371V$

Explanation:

The width of the truck is given as 79inch but we need to convert to meter for consistency, then

The width= 79inch × 0.0254=2.0066 metres.

Now we can calculate the induced Emf using expresion below;

Then the $induced EMF= B L v$

Where B= magnetic field component

L= width

V= velocity

=(40*10^-6) × (42) × (2.0066)

=0.003371V

Therefore, the magnitude emf that is induced between the driver and passenger sides of the truck is 0.003371V

A projectile is fired with a velocity of 22 m/s at an angle of 25°. What is the vertical component of the velocity?

7nadin3 [17]

Answer:

Vertical component of velocity is 9.29 m/s

Explanation:

Given that,

Velocity of projection of a projectile, v = 22 m/s

It is fired at an angle of 22°

The horizontal component of velocity is v cosθ

The vertical component of velocity is v sinθ

So, vertical component is given by :

$v_y=v\ sin(25)$

$v_y=22\ m/s\times\ sin(25)$

$v_y=9.29\ m/s$

Hence, the vertical component of the velocity is 9.29 m/s
