40 million
1. Approximately how many people watch the March Madness tournament? There are more than 140 million that watch March Madness.
Answer:
Moving a unit "positive" test charge from A to B will result in a reduction in potential
V = K Q / R potential at a point
V2 - V1 = K Q (1 / .4 - 1 / .15) = = k Q (.15 - .4) / .06 = -4.17 K Q
V2 - V1 = -4.17 * 9 & 10E9 * 6.25 E-8
V2 - V1 = -4.17 * 562.5 J/C
V = - 2346 Volts
Rank of the radiation particles according to their ability to penetrate solid objects, from the best able to penetrate to the least able to penetrate:
C ) gamma particle, beta particle, alpha particle.
Answer:
Option E is correct.
There must be a horizontal wind opposite the direction of the stone's motion, because ignoring air resistance when calculating the horizontal range would yield a value greater than 32 m.
Explanation:
Normally, ignoring air resistance, for projectile motion, the range (horizontal distance teavelled) of the motion is given as
R = (u² sin 2θ)/g
where
u = initial velocity of the projectile = 20 m/s
θ = angle above the horizontal at which the projectile was launched = 30°
g = acceleration due to gravity = 9.8 m/s²
R = (30² sin 60°) ÷ 9.8
R = 78.53 m
So, Normally, the stone should travel a horizontal distance of 78.53 m. So, travelling a horizontal distance of 32 m (less than half of what the range should be without air resistance) means that, the motion of the stone was impeded, hence, option E is correct.
There must be a horizontal wind opposite the direction of the stone's motion, because ignoring air resistance when calculating the horizontal range would yield a value greater than 32 m.
Hope this Helps!!!
The dependent variable in this experiment is the mass of each liquid.
Density is the ratio of mass to volume of a substance. In this experiment, since the volume of each liquid is given, to get density, mass of each quantity must be known which is the outcome.
Density also depend on the mass of a substance and density can easily be identified by mass if all the substance in question have the same volume.
In this experiment, all the liquid have the same volume. Since the student want to list them in order from the least dense to the most dense, how dense the liquid are will be a function of the differences in liquid mass.
The least dense liquid will float. That is, will be at the top most of the container. While the most dense will be at the bottom of the container.
Therefore, the dependent variable in this experiment is the mass of each liquid
