How many miles can you get on one tank of gas if your tank holds 18 gallons and you get 22 miles per

2 answers:

Multiply the two. The units will cancel out. 22 miles per gallon can be expressed as 22 miles / 1 gallon, so you can write the following:
18 gallons * 22 miles / 1 gallon
Which simplifies to 18 * 22 miles = 396 miles.

Answer:

Q=mc∆tita.

4780J= m × 2445J/kg/°C × 5.43°C

4780J= m× 13276.35J/kg

1. This image shows the various forces acting on a block of rock situated on a rock slope. What does arrow 4 represent?

Gelneren [198K]

Answer:

B. Gravitational force

Explanation:

The gravitational force of an object (also called weight) is given by

$F=mg$

where m is the mass of the object and g is the acceleration of gravity, and it always points in the downward direction.

In this problem, the arrow labelled with 4 is the only force pointing downward: therefore, it must be the gravitational force.

The other arrows represent:

1 --> component of the gravitational force parallel to the plane

2 --> force of friction

3 --> component of the gravitational force perpendicular to the plane

MAVERICK [17]

Answer:

y = 0m

y0 = 166m

v0y = 0 m/s

g = 9.8 m/s^2

t = ?

Solve for t:

y = y0 + v0y*t - (0.5)gt^2

0 = 166 - (0.5)(9.8)t^2

t = 5.82 s

Now, using time, we can solve for the range using the equation:

x = vx(t)

x = (40)(5.82)

x = 232.8 m

The impact horizontal component of velocity will be 40 m/s as velocity in terms of x is always constant. To find the impact vertical component of velocity, we use the equation:

v = v0y - gt

v = 0 - (9.8)(5.82)

v = -57.04 m/s
