If it takes Tanya 9.4 hours to get to her cousin's house while driving an average of 40 mph, how far away does her

Rufina [12.5K]

Answer:

376 miles

Explanation:

speed = distance / time

therefore distance = speed * time

distance = 40 miles/hr * 9.4 hr

then

distance = 375 miles

A box is sitting on a 2 m long board at one end. A worker picks up the board at the end with the box so it makes an angle with t

Vlada [557]

Answer:

Explanation:

When the box is on the ramp , component of its weight along the ramp

= mg sinθ

Friction force acting on it in upward direction

=μ mg cosθ

For sliding

μ mg cosθ < mg sinθ

μ cosθ < sinθ

.5 x cos35 < sin35

.41 < .57

So the box will slide

When sliding starts , kinetic friction acts

Net force in downward direction

mgsinθ - μ mg cosθ

acceleration

= gsinθ - μ g cosθ

= 5.62 - .3 x 9.8 x cos35

= 5.62 - 2.4

= 3.22 m /s²

A treasure chest full of silver and gold coins is being lifted from a pirate ship to the shore using two ropes as shown in the f

stiks02 [169]

The tension in rope C is determined as 122.23 N.

<h3>Tension in rope C</h3>

The tension in rope C is calculated as follows;

B² = A² + C²

C² = B² - A²

C² = (752²) - (742²)

C² = 14,940

C = √14,940

C = 122.23 N

Thus, the tension in rope C is determined as 122.23 N.

How is light energy different from both sound and heat energy?

SIZIF [17.4K]

Light always travels in a straight line when going through a single medium, any substance through which a light wave can travel. In some mediums, such as air, light travels quickly. ... Heat, light and sound are similar to each other. They are forms of energy and they travel in waves.

Four different resistors have various amounts of electric current flowing through them.

salantis [7]

Answer:

Order will be Forth resistor , first resistor, second resistor, third resistor

Explanation:

We have given four different resistance and current flowing through them

In first resistor resistance R = 4 ohm and current flowing i = 6 A

According to ohm's law voltage = current × resistance = 6×4 = 24 volt

In second resistor resistance R = 2 ohm and current i = 9 A

So voltage V = 9×2 = 18 volt

In third resistor resistance R = 2 ohm and current i = 3 A

So voltage V = 3×2 = 6 volt

In forth resistor resistance R = 8 ohm and current i = 8 A

So voltage V = 8×8 = 64 volt

So order of highest voltage to lowest voltage is 64,24,18,6

Forth resistor , first resistor, second resistor, third resistor
