To develop this problem it is necessary to use the expression that allows us to convert the degrees Celsius to Fahrenheit. The expression that allows to realize it is given mathematically by:

\°F = (\°C* \frac{9}{5}) + 32

In this way for 33.2 °C:

\°F = (\°C * \frac{9}{5}) + 32

\°F = (32.2* \frac{9}{5}) + 32

\°F = 91.76

In this way for 38.2°C

\°F = (\°C * \frac{9}{5}) + 32

\°F = (38.2* \frac{9}{5}) + 32

\°F = 91.76

Expressed in a range term, we can say that the measure in degrees Fahrenheit is:

[91.76\° F , 100.76\° F]

Vitek1552 [10]

Answer:

1. 2160 J

2. 2940 J

3. 64 J

Explanation:

1. Determination of the work done.

Weight (W) = 180 N

Height (h) = 12 m

Workdone =?

Wd = W × h

Wd = 180 × 12

Wd = 2160 J

Thus, the Workdone is 2160 J

2. Determination of the work done.

Mass (m) = 50 Kg

Height (h) = 6 m

Acceleration due to gravity (g) = 9.8 m/s²

Workdone =?

Wd = mgh

Wd = 50 × 9.8 × 6

Wd = 2940 J

Thus, the Workdone is 2940 J

3. Determination of the work done.

Force (F) = 16 N

Distance (d) = 4 m

Workdone =?

Wd = F × d

Wd = 16 × 4

Wd = 64 J

Thus, the Workdone is 64 J

A sports car starts from rest at an intersection and accelerates toward the east on a straight road at 8.0 m/s2. Just as the spo
kobusy [5.1K]

Answer:

a)  t = 4.5 s , b)    x = 81 m

Explanation:

a) For this problem we will use kinematic relationships

For the car

        x = v₀ t + ½ a₁ t²

Since the car kicks from rest, the initial speed is zero

         x = ½ a₁ t²

For the bus

        v₂ = x / t

       x = v₂ t

At the point where they are located it has the same position, so we can match the equation

       ½ a₁1 t² = v₂ t

       ½ a₁ t = v₂

        t = 2 v₂ / a₁

Let's calculate

       t = 2 18 /8.0

       t = 4.5 s

b) to find the position

        x = v₂ t

        x = 18   4.5

        x = 81 m

With what average speed must you drive your car if your average speed for the entire 23 km is to be 25 km/h?
aksik [14]

Answer:

25km/h

Explanation:

This is a trick question, the average speed in this case does not really depend on calculation or extrapolation, it just refers to an event that is yet to occur,

In other words, if you want to achieve an average speed of 25km/h for 23km, then you should drive your car at a constant speed of 25km/h, any variation in speed may cause a change in your average speed at the end.
