Answer:
750cm³
Explanation:
volume = length × width × height
15 × 10 × 5 = 750
750cm³
Answer:
(2) −1 e
Explanation:
A quark is the lightest elementary particles which form hadron such as proton and neutron. A quark has fractional charge.
Up, charm and top quarks have
charge where as down, strange and bottom quarks have
charge.
The antiparticle of up quark is antiup quark and has charge
charge.
The antiparticle of down quark is antidown quark and has charge
charge.
An antibaryon is composed of two anti-up quark and one anti-down quark.
Net charge of the anti-baryon is:
Thus, antibaryon has -1e charge.
Answer:
6:50 PM
Explanation:
The Moon continually moves on ahead in its orbit while the Earth rotates. So 24 hours after, the Earth has rotated back around to the same place it was the night before, while the Moon has gone on ahead. assume of it like the second hand on an analog watch, it’s going around the face of the clock much faster than the minute hand, but each time the second hand goes around, the minute hand has moved, and so it takes an extra second to line back up with the minute hand. Because the Moon has moved 13 degrees or so since its last moon rise, it’s going to take another hour or so for the Earth to catch back up to the Moon’s new location, delaying the Moon's rising above your horizons by ~50 minutes each day.
Given :
The ball of a ballpoint pen is 0.5 mm in diameter and has an ASTM grain size of 12.
To Find :
How many grains are there in the ball?
Solution :
Volume of ball of the ballpoint is :

Now, grain size of 12 has about 520000 grains/mm³.
Therefore, number of grains are :

Answer:
116 N.
Explanation:
Given,
mass of the ball, m = 0.145 Kg
initial speed = 0 m/s
Final speed = 40 m/s
time = 50 ms = 0.05 s
Force is equal to change in momentum per unit time


F = 116 N
Force of the pitcher hand on the ball is equal to 116 N.
