Answer:
The Velocity at which it travels, and the Distance from start to finish.
Explanation:
Calculate V*D=T which is Velocity*Distance=Time.
All of them are examples of energy being transferred by waves<span />
Answer:
The radius of the sphere is 3.6 m.
Explanation:
Given that,
Potential of first sphere = 450 V
Radial distance = 7.2 m
If the potential of sphere =150 V
We need to calculate the radius
Using formula for potential
For 450 V
....(I)
For 150 V
....(II)
Divided equation (I) by equation (II)
Hence, The radius of the sphere is 3.6 m.
Answer:
A combined reaction is when two or more reagents combine __ to form a product
Explanation:
A combination or synthesis reaction, consists of the formation of a substance from the reaction of two or more substances.
Example: A + B -> C
2Na + Cl2 ---> 2NaCl (sodium chloride formation reaction)
Answer:
F = 196 N
Explanation:
For this exercise we will use Newton's second law, we define a reference system with the x axis in the direction of movement of the stones and the y axis vertically
Y axis
N- W = 0
N = mg
X axis
F -fr = ma
In this case, they ask us for the force to keep moving, so the stones go at constant speed, which implies that the acceleration is zero.
F- fr = 0
F = fr
the friction force has the equation
fr = μ N
fr = μ mg
we substitute
F = μ mg
let's calculate
F = 0.80 9.8 25
F = 196 N
