Answer:
V=14.9 m/s
Explanation:
In order to solve this problem, we are going to use the formulas of parabolic motion.
The velocity X-component of the ball is given by:

The motion on the X axis is a constant velocity motion so:

The whole trajectory of the ball takes 1.48 seconds
We know that:

Knowing the X and Y components of the velocity, we can calculate its magnitude by:

Answer:
zero times greater
Explanation:
Coffee's pH level is 5
Pure water's pH level is 7
Answer:B
Explanation:
For work to be done, the object must move some distance as a result of a force
Answer:
E=1100V/m
Explanation:
Given required <u>solution</u>
V=6.6v E=? V=Ed ; V is the potential difference between
d=D/2=1.2cm/2=0.6cm=0.006m the halfway
E is the electric field between the two
plates.
d is the distance between the halfway.
So we can use the above formula to calculate the electric field.
V=Ed from this E=V/d substitute the values from the given equation.
E=6.6v/0.006m
E= 1100 v/m
Answer:
Option D is the correct answer.
Explanation:
Refer the figure given.
By Pascal's principle we have

F2 = 2 x 10⁴ N

Substituting

Option D is the correct answer.
