Answer:
1/9 E0
Explanation:
The computation is shown below:
As we know that
where,
E = Electric field strength
k = Coulomb's constant
Q = charge on the sphere
r = distance from the center of the sphere
It is given that
The radius of the larger sphere is three times larger than that of the smaller sphere i.e
hence, the last option is correct
Answer:
14.8m
Explanation:
Given parameters:
Initial speed = 17m/s
Unknown:
Maximum height = ?
Solution:
At the maximum height, the final speed will be 0m/s;
We use of the kinematics equation to solve this problem.
V² = U² - 2gH
V is the final velocity
U is the initial velocity
g is the acceleration due to gravity
H is the height
0² = 17² - (2 x 9.8 x h )
0 = 289 - (9.6h)
-289 = -19.6h
h = 14.8m
In order to find the displacement of something, you can calculate it by subtracting the initial distance from the final distance.
7-5 =2
so the mouse would’ve walked a displacement of 2cm

We have that Zero signifies a perfect circle shape and 1 shows it maximum out of order shape.
From the question we are told
What does it mean when the orbital eccentricity of a planet is close to 1
Generally
Eccentricity
This in its simplest definition means to be eccentric which means to be a bit out of order or for the given subject at hand means to be a bit out of shape
Naturally the Eccentricity that an object possess is defined by two number 0(zero) to 1(one)
Where
Zero signifies a perfect circle shape and 1 shows it maximum out of order shape
