Fe=k|q1q2| / r^2
(k is the electrostatic constant which has a value of 8.99x10^9 Nm^2/c^2, r is the distance between the charges and q is the quantity of the charges.)
Remember the rule of thumb that every person learns in Elementary Science? You must do multiple experiments in order to get to a conclusion. In order for a conclusion to be valid you must test the conclusion multiple times. You wouldn't want a doctor to just test an aspirin 1 time on 1 patient and say yes it works correct? No, you would want him/her to test on multiple patients in multiple settings and conditions so that when you take an aspirin you know that it will work for what you are taking it for. So ..... with all that being said.....Your answer is (A). The results are more likely to have errors.
Answer:
Solution:
we have given the equation of motion is x(t)=8sint [where t in seconds and x in centimeter]
Position, velocity and acceleration are all based on the equation of motion.
The equation represents the position. The first derivative gives the velocity and the 2nd derivative gives the acceleration.
x(t)=8sint
x'(t)=8cost
x"(t)=-8sint
now at time t=2pi/3,
position, x(t)=8sin(2pi/3)=4*squart(3)cm.
velocity, x'(t)=8cos(2pi/3)==4cm/s
acceleration, x"(t)==8sin(2pi/3)=-4cm/s^2
so at present the direction is in y-axis.
The answer is D) The outcome of the experiment will be non observable
Answer:
The wedge balances propelled force.
Explanation:
According to the laws of motion, when appropriate weight is employed properly, a ball can move a truck. The same basic functions apply in this scenario. You often find a woodcutter raising the axe and letting it fall into the wood. This allows force to equally generate at both sides of the axe, splitting the wood apart.
