Answer:
Order of 10^(-35) m.
Explanation:
The string theory is a theoretical concept whereby the very small particles of particle physics are replaced by one dimensional objects which are called strings. This theory is also applicable to black hole physics, nuclear physics, cosmology, etc.
Now, 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.
This is because the length of the scale is assumed to be on the order of the Planck length, or 10^(−35) meters which is the scale at which the effects of quantum gravity are usually believed to become very significant.
Answer:
F = −10093.41 N
Explanation:
Given that,
Mass of a baseball, m = 143 g = 0.143 kg
Initial speed of the baseball, u = +38.8 m/s
The hitter's bat is in contact with the ball for 1.20 ms and then travels straight back to the pitcher's mound at a speed of 45.9 m/s, v = -45.9 m/s
We need to find the average force exerted on the ball by the bat. So, Force is given by :
a is acceleration
So, the average force exerted on the ball by the bat has a magnitude of 10093.41 N.
I believe it would be x because you are trying to find the width of the wave but i could be wrong
C) The change of velocity over time
Answer:
According to Ohm's law :
Where,
V is the potential difference or voltage.
I is the current flowing in a circuit.
R is the resistance.
The SI unit of potential difference is Volt. It is denoted as V.
The SI unit of current is Ampere. It is denoted as A.
The unit for resistance is :
It is equivalent to Ohm or .
Hence, the correct option is (a) " volt ÷ ampere ".
