The relationship between the stiffness of a medium and the speed of the wave is directly proportional. Because molecules are closer in a stiff medium, an increase of stiffness in a medium would also result to an increase in which a wave travels.
Answer:
1/2
Explanation:
This will lead us to simultaneous equation since there are two person involved doing the same job each day.
For Ted;
Since Ted can wax 8 cars or wash 10 cars in a day. Mathematically, we have
8x + 10w = 1... (1)
Where x is for waxing cars, w is for washing cars
Similarly for Tom,
Tom can wax 3 cars or wash 5 cars in a day as well, this gives us;
3x + 5w = 1... (2)
Equating 1 and 2, we have;
8x + 10w = 1... (1)
3x + 5w = 1... (2)
Using elimination method, we will multiply eqn 1 by 3 and eqn 2 by 8 to have;
24x + 30w = 3
24x + 40w = 8
Subtracting eqn 4 from 5 we have;
30w - 40w = 3 - 8
-10w = -5
w = 5/10
w = 1/2
Therefore each man's opportunity cost of washing a car is 1/2

answer: No charge of the length of the bonds expected because the rod did not touch the charge source ( option A )
Explanation:
When the Charge is first, Furthest away and second and closest to the source charge. The spring like bonds can be said to have No charge of the length of the bonds expected because the rod did not touch the charge source when Furthest away the bond with charge will be less effective
Answer:
MOSE
Explanation:
According to the given statement 3.77 m/s² is the acceleration of the block.
An object's motion is altered by a net force; the larger the net power, the higher the acceleration. To accelerate at the same rate as less massive objects, higher net forces are needed.
The capacity to acceleration demonstrates how quickly an athlete can increase or decrease their velocity over a specific period of time or over a specific distance after starting off at rest. For sprinting but in all ball games, it is a crucial skill. The main reasons of poor speed include problems with the delivery of air and fuel as well as sensor problems. Low power, meanwhile, can also be brought on by mechanical problems.
m = 0.52-kg
F = 2.63 N - 0.67 N
= 1.96 N (Net Force)
a or acceleration
Formula and solution:
a = F/
a = 1.96 kg.m/s² ÷ 0.52 kg
a = 3.77 m/s²

Answer:
a = 3.77 m/s²
Explanation:
Given:
m = 0.52-kg
F = 2.63 N - 0.67 N = 1.96 N (Net Force)
Unknown:
a or acceleration
Formula and solution:
a = F/m
a = 1.96 kg.m/s² ÷ 0.52 kg
Final Answer:
a = 3.77 m/s²
There are the same unit in the solution which is kg so we cancel it then the rest which is m/s² combine it in the quotient of 1.96 kg.m/s² or N and 0.52 kg which is 3.769 then round off to nearest hundredths so the final answer is 3.77 m/s²
