A nuclear particle with no charge is a neutron
Answer:
Acceleration
Explanation:
For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero). If the acceleration is positive, then the line is an upward sloping line (i.e., the slope is positive).
Answer:
d = 2.45 meters
Explanation:
Mass of the ball, m = 0.5 kg
Radius of the circle, r = 0.16 m
The angular speed of the ball around the circle is, 
The attached figure shows the whole scenario. Let 
is the force acting on the ball in tangential direction. The forces will balanced each other at equilibrium.
In horizontal direction,
................(1)
In vertical direction,
...............(2)
From equation (1) and (2) :
Also,
d = 2.45 meters
So, the value of d is 2.45 meters. Hence, this is the required solution.
<span>The metric
system is the oldest name for the international system of units. The answer is <u>a.
True. </u>SI unit or the international systems of units are based on seven
basic units; the meter, kilogram, second, ampere, Kelvin, candela and mole. All
of these basic units are divided into multiples by a power of ten. For example
in meters, 1 meter is equal to: 1000 millimeter, 100 centimeter, 10 decimeter,
0.1 decameter, 0.01 hectometer, 0.001 kilometer and so on and so forth.</span>
The answer is D.
Most of the rotational and orbital motions in the solar system are in the same "eastward" direction. Motions in this direction are referred to as direct motions while motions in the opposite direction are referred to as retrograde.
Retrograde motion is the apparent backward motion of a planet caused by its being lapped by another planet or vice versa. Both planet move in a direct eastward motion around the sun, but the planet with the inside (smaller) orbit moves faster than the planet on the outside (larger orbit), and when it passes the slower moving planet, each sees the other one as apparently moving backward relative to its motion around the sky.
