Answer:

Step-by-step explanation:

63 - (-4) = 63 + 4 = 67 <== a difference of 67

or think of it this way..

if its at 63, u subtract 63 just to get to 0....but then u have to subtract 4 more to get to -4......making a difference of 67

kate takes 48 minutes to get to the park. if she gets to the park at 2:32 what time did she leave for the park
olya-2409 [2.1K]

Answer:

1:44

Step-by-step explanation:

You can subtract 32 minutes from 2:32 to get 2:00.

Since you only subtracted 32, subtract 16 (16+32=48) from 60, since 60 minutes is one hour, to get 1:44

two-point charges are 10.0 cm apart and have charges of 2.0 uc and -2.0uc respectively What is the magnitude of the electrical f
maks197457 [2]

Answer:

The electric field generated by a point charge is given by:

where

is the Coulomb's constant

Q is the charge

r is the distance from the charge

We want to know the net electric field at the midpoint between the two charges, so at a distance of r=5.0 cm=0.05 m from each of them. 

Let's calculate first the electric field generated by the positive charge at that point:

where the positive sign means its direction is away from the charge.

while the electric field generated by the negative charge is:

where the negative sign means its direction is toward the charge.

If we assume that the positive charge is on the left and the negative charge is on the right, we see that E1 is directed to the right, and E2 is directed to the right as well. This means that the net electric field at the midpoint between the two charges is just the sum of the two fields:

What is the value of x using the Pythagorean theorem?
Vesnalui [34]
A^2+b^2= c^2

Plug in the points. the longest side is always c.

95.2^2+ b^2= 168^2.

Square the numbers.

9063.04+ b^2= 28224

Subtract 9063.04 on both sides.

b^2= 19160.96

Find the square root. 

b= 138.423119456

Or, b= 138.4 (rounded down)

I hope this helps!
