Answer: 2.5x10^8 kilometers
Explanation:
Given that:
Distance between the earth and the sun = 2.5x10¹¹metres
Convert distance in metres to kilometers
Recall that 1000 metres = 1 kilometers
So, 2.5x10¹¹metres = Z kilometers
To get the value of Z, cross multiply
Z km x 1000 m = (2.5x10¹¹metres x 1km)
1000Z = 2.5 x 10^11
Divide both sides by Z
1000Z/1000 = 2.5 x 10^11/1000
Z = 2.5x10^8km
Thus, the distance between the earth and the sun is about 2.5x10^8km
The answer is B. Weak electrolytes are weak because they only partially dissociate into ions in water.

Answer:
Following are the solution to the given points:
Explanation:
For point a:
Find the schematic of the empty body and in attachment. Upon on ball during the pitch only two forces act:
The strength of the pitcher F is applied that operates horizontally. Its gravity force acting on an object is termed weight, which value is where m denotes mass, and g the acceleration of gravity.
For point b:

First, they must find that ball's acceleration. You can use the SUVAT equation to achieve that
where

Solving for a,

Calculating the mass:

Calculating the force:

For point c:
0.195 times the pitcher's weight

Solving for W:

Now the force of Part B could be defined as the fraction of the mass of the pitcher:

Different wavelengths of light are seen as colors
Answer:
The height is 
Explanation:
From the question we are told that
The combined mass of the child and the sled is 
The speed of the sled is 
Generally applying SOHCAHTOA on the slope which the combined mass is down from
Here the length of the slope(L) where the combined mass slides through is the hypotenuses
while the height(h) of the height of the slope is the opposite
Hence from SOHCAHTOA

=> 
Generally from the kinematic equation we have that

Here the u is the initial velocity of the combined mass which is zero since it started from rest
and a is the acceleration of the combined mass which is mathematically evaluated as
