Note that
1 yd = 0.9144 m

Therefore,
The length of an American Football field is
(100 yds)*(09144 m/yd) = 91.44 m

Because the soccer field is 110 m long, its length exceeds the American Football Field by
100 - 91.44 = 8.56 m
or
(8.56/.9144) =  9.36 yd
This difference is equivalent to (8.56/91.44)*100 = 9.4%

Answer:
The Soccer Field is longer by
8.56 m, or
9.36 yd, or
9.4%

Find the electric field at a point midway between two charges of +40.0 x 10^-9 c and.+60.0 x 10^-9 c
PIT_PIT [208]
Missing part in the text: "...the charges are <span>separated by a distance of 30.0 cm."
</span>
Solution:
The point midway between the two charges is located 15.0 cm from one charge and 15.0 from the other charge. The electric field generated by each of the charges is
E=k_e \frac{q}{r^2}
where
ke is the Coulomb's constant
Q is the value of the charge
r is the distance of the point at which we calculate the field from the charge (so, in this problem, r=15.0 cm=0.15 m).

Let's calculate the electric field generated by the first charge:
E_1 = (8.99 \cdot 10^9 Nm^2 C^{-2} ) \frac{+40.0 \cdot 10^{-9} C}{(0.15 m)^2}=1.6 \cdot 10^4 N/C

While the electric field generated by the second charge is
E_2 = (8.99 \cdot 10^9 N m^2 C^{-2} ) \frac{+60.0 \cdot 10^{-9} C}{(0.15 m)^2}=2.4 \cdot 10^4 N/C

Both charges are positive, this means that both electric fields are directed toward the charge. Therefore, at the point midway between the two charges the two electric fields have opposite direction, so the total electric field at that point is given by the difference between the two fields:
E=E_2 - E_1 = 2.4 \cdot 10^4 N/C - 1.6 \cdot 10^4 N/C = 8000 N/C

Pam rubs a balloon on her head and then holds the balloon up against a wall. Why might the balloon stick to the wall?
gregori [183]

Answer:

It sticks to the wall due to electrostatics.

Explanation:

When pam rubs a balloon against his hair, and holds it up against the wall, he is basically adding a surplus of electrons which are negative charges to the surface of the balloon.

This motion would make the wall the more positively charged than the balloon. Therefore, when the two charges come in contact with each other, the balloon will stick to the wall because of the rule in electrostatics that opposite charges attract each other.

A young boy of mass m = 25 kg sits on a coiled spring that has been compressed to a length 0.4 m shorter than its uncompressed l
rewona [7]
The spring's elastic potential energy is converted into elastic potential energy of the boy.
Potential energy = elastic energy
mgh = 1/2 kx²
k = (2 * 25 * 9.81 * 0.5) / 0.4²
k = 1533 N/m

We will apply
2as = v² - u², with u = 0
a = F/m
F = kx
a = kx/m

v = √(2 x 0.4 x (0.4 x 1533 / 25))
v = 4.43 m/s
