Answer:

a) -35.6°C

b) 237.4 K

Explanation:

**To convert temperature from degree celsius to degree fahrenheit, use the formula below:**

**a) Therefore to convert -32°F to celsius, substitute it into the celsius**

**b) To covert to the Kelvin scale, use the formula below**

Humans did not create dogs.

Humans have never created any new living species.

So far, the only one who can do that is You Know Who.

**Answer:**

For the first one its about 25 feet

**Explanation:**

Total displacement along the length of mountain is given as

L = 235 m

angle of mountain with horizontal = 35 degree

now we will have horizontal displacement as

x = L cos35

x = 235 cos35 = 192.5 m

similarly for vertical displacement we can say

y = L sin35

y = 235 sin35 = 134.8 m

**The initial velocity of the ball is 1.01 m/s**

**Explanation:**

The motion of the ball rolling off the desk is a projectile motion, which consists of two independent motions:

- A uniform horizontal motion with constant horizontal velocity

- A vertical accelerated motion with constant acceleration (, acceleration due to gravity)

We start by analyzing the vertical motion: we can find the time of flight of the ball by using the following suvat equation

where

s = 1.20 m is the vertical displacement (the height of the desk)

u = 0 is the initial vertical velocity

t is the time of flight

Solving for t,

Now we analyze the horizontal motion. We know that the ball covers a horizontal distance of

d = 0.50 m

in a time

t = 0.495 s

Therefore, since the horizontal velocity is constant, we can calculate it as

So, the ball rolls off the table at 1.01 m/s.
