Change in direction, change on speedo both
Answer: The multiplication factor is 72.136 cm. This will give you the unit conversion when multiplied with 28.4 inch
Explanation:
1 inch = 2.54 cm
28.4 inches = x cm
Xcm= (28.4 inches × 2.54cm)/1 inch
X= 72.136
Answer:
0.08 ampere
Explanation:
Power = voltage x current
W = v x I
Given
Power = 10.0 w
V = 120v
I = ?
Therefore
10.0 = 120 x I
Divide both sides by by 120
10.0/120 = 120/120 x I
0.08 = I
I = 0.08 ampere
Answer:
D
Explanation:
F = G m1 m2 / r^2 now double r
F = G m1m1/ (2r)^2
F = 1/4 G m1m2/r^2 <===== this is 1/4 of the original
Answer:
A chemical reaction
Explanation:
In a physical change the chemical composition of a matter stays the same. One example is a change in state of matter. Consider water, you can heat it to vapour and cool it to form ice but you can get the exact same mass and colour after any physical change happens.
To form a two or more substance an internal arrangement of atoms must happen. For that chemical change should occur as only in chemical reactions atoms are rearrange to form new substances.
