According to string theory, six space-time dimensions cannot be measured except as quantum numbers of internal particle properti

m_a_m_a [10]

Answer:

$10^{-35}\ meters$

Explanation:

The string theory is a theoretical concept, the very small particles of particle physics are rep[laced by strings. This theory also applies to black hole physics, nuclear physics, cosmology etc.

According to string theory, six space-time dimensions cannot be measured except as quantum numbers of internal particle properties because they are curled up in size of the order of $10^{-35}\ m$ .

The length of the scale is assumed to be on the order of $10^{-35}\ m$ . Hence, the correct option is (a).

What is the electric force acting between two charges of 0.0042 C and −0.0050 C that are 0.0030 m apart?

Black_prince [1.1K]

Answer:

A.−2.1 × 10^10 N

Explanation:

Using the formula;

E = k Q1Q2/d²

Where;

E is the electrical force

k is the constant

Q1, Q2 are the two charges and

d is the distance between the two charges

Therefore;

E = (9 x 10^9) × (0.0042) × (-0.0050) / (0.0030)²

= -2.1 x 10^10 N

Therefore; electrical force acting between the two charges is -2.1 x 10^10 N.

An AC generator supplies 44 rms volts to a 60-Ω resistor at 60 Hz. What is the maximum current in the resistor?

Brilliant_brown [7]

Answer:

1.0639 A

Explanation:

We have given rms voltage V = 44 volt

Resistance = 60 ohm

According to ohm's law $V=iR$

So $44=i\times 60$

$i=\frac{44}{60}=0.7333A$ this is the rms current but we have to find the maximum current

So maximum current $i_m=\sqrt{2}i_{rms}=1.414\times 0.7333=1.03693A$

What is a push or pull that acts on a object

sdas [7]

Answer:

Force is defined as a push or pull acting on an object. Forces include gravity, friction, and applied force. Force causes changes in the speed or direction of motion. These changes are called acceleration.
