This causes one object to have an overall positive charge and the other object to have an overall negative charge. Like charges repel Unlike charges attract Neutral objects are attracted to both positively and negatively charged
11. The velocity of a body of mass m changes by an amount ∆v in a time ∆t. The impulse given to the body is equal to A. B. C. D. m∆t . ∆v .
The concentration is measured in molarity. Molarity is the measure of moles of solute per liter of solution. The rate law helps one find solution's reaction order. If the reaction order is zero, the graphical representation is concentration vs. time, and the slope of the line is the negative rate constant. If the reaction is first order, its graphical representation is seen as ln[A] (natural log of concentration) vs. time, and the slope of its like is also the negative rate constant.
Description and Theories A. Principles and Theories Used to Obtain our Result An conventional spring, when subjected the weight (w=mg) of an object at one of its terminations, will displace a certain distance, x, with an equal and opposite force, F, being created in the spring of which opposes the pull of the weight. This conventional spring will become significantly distorted if it is subjected to a large enough weight and the force, F, will only be able to return the spring to its original configuration once the burden is removed. The force that will restore the spring to its original configuration is directly proportional to the displacement that occurred. The following equation represents this relationship where k denotes the spring constant or stiffness of the spring, F=-kx Since x symbolizes the displacement or change in the length of the spring the above equation can now be surmised in the following manner, F=mg=-k∆l This new form makes it evident that a linear proportion exists between the plot of F as function of changing in length, ∆, thus confirming the spring does in fact obey Hooke’s Law.
Is this a statistically significant correlation? Provide a rationale for your answer. This represents a moderate negative relationship. It is statistically significant at the 1% level of significance as indicated in the table. (** p < 0.01) 3.
Give a complete explanation for the "Negative ..._______The negative exponent rule states that when a variable or number is raised to a negative exponent, the expression may be rewritten as one divided the variable or number raised to that positive exponent. A negative exponent indicates “reciprocal”. When a factor is moved from the denominator to the numerator or from the numerator to the denominator, the sign of the exponent changes.9. Give a complete explanation for the "Fraction raised to... ______In the fraction raised to a negative exponent rule, with fractions in the form a over b, a is not equal to zero and b is not equal to zero. A over B with a negative
The distance between the forces is given by the Coulombs law through the use of the formula F=kq1q2/r2.0.1newtons = 8.99*109*3.2*10-6*7.7*10-7/r2 R= 555.78 Answer to question 3 • Potential difference between the two plates is equal to velocity which is equal to 6.0*106m/s • Force = mass *acceleration = 1.4*10-13*6.0*106 = -8254 nektons The speed of the particles are computed by the formula V=ED. This is equal to 8.5*10-6*0.15. This is equal to 84.1 Answer to question 4 Voltage = current *resistance. This implies that in this case while V is 5.0 and resistance is 1.0*103, current will be equal to 5/1.0*103, = 500 amps B the direction of the conventional current provides the electric charge movement from the positive side of the battery to its negative side as in indicated in the diagram below Answer to question 5 • This section focuses on the equivalent resistance of a circuit. The equivalent resistance will be equal to (5.0*102+1.00*103)2.
How does average speed relate to the distance covered and the time taken for travel? * The average speed is way different than the distance, but a little similar to time. For example: the time was 2.53 and the speed was 2.42 2. Should the recorded average speed represent the maximum speed for each event? * It depends, if the object was traveling at a constant speed, then yes.
42. What does it mean if two quantities vary inversely? To vary inversely means as one variable goes up the other would go down and vice versa. 43. Explain what is meant by combined variation.
58. Yes, a cars velocity is positive or negative with respect to its direction of motion from some point of reference. One direction of motion is defined as positive, and velocities in that direction are considered positive. The opposite direction of motion is considered negative: all velocities in that direction are negative. An object undergoing positive acceleration is either increasing its velocity in the positive direction or reducing its velocity in the negative direction.
