An effective early childhood curriculum can be learning how to read and write. Without learning how to read, we wouldn’t be able to communicate through this app, or through online school. We wouldn’t know directions, and we wouldn’t be able to enjoy stories. If we didn’t know how to write, I would not be able to help you figure out the answer to this problem, and your teacher wouldn’t be able to grade anything. Think about it, you ir entire education is based of being able to read and write.
Hope this helps :)
Answer:
the maximum force will be equal to 134.84 N
Explanation:
We have given mass m = 43 kg
Coefficient of static friction
Acceleration due to gravity
We have to find the maximum force which , when applied there is no movement of crates
This maximum force will be equal to frictional force
Frictional force is given by
So the maximum force will be equal to 134.84 N
Answer:
C
Explanation:
When A and B come in contact with each other, +12 - 12 = 0 so their changes cancel.
Now C has a charge of +12
When A and C come together they each have an equal share of that 12, so each of them has 6
So the answer is
A B C
6 0 6
which is C

Answer:
1438.4 N
Explanation:
Applying,
F = kqq'/r²................... Equation 1
Where F = Electrostatic force on the balloons, k = coulomb's constant, q = charge on the first balloon, q' = charge on the second balloon, r = distance between the two ballons.
From the question,
Given: q = q' = 4.0×10⁻⁵ C, r = 0.1 m
Constant: k = 8.99×10⁹ Nm²/C²
Substitute these values into equation 1
F = ( 4.0×10⁻⁵×4.0×10⁻⁵×8.99×10⁹)/0.1²
F = 14.384/0.01
F = 1438.4 N
