Magnitude and Direction of Electric Fields??How would you do the following? A small object A, electrically charged, creates an electric field. At a point P located 0.250m directly north of A, the field has a value of 40.0N/C directed to the south. What is the charge of object A? (a)1.11×10^-9 C (b)-1.11x10^-9 C (c)2.78x10^-10 C (d)-2.78x10^-10 C (e)5.75x10^12 C (f)-5.75x10^12 C

Answers

Answer 1

Answer: The right answer for the question that is being asked and shown above is that: "(d)-2.78x10^-10 C." A small object A, electrically charged, creates an electric field. At a point P located 0.250m directly north of A, the field has a value of 40.0N/C directed to the south.

Which term refers to the time interval between the passage of successive wave crests? a. wave height
b. wave period
c. wave speed
d. wavelength

Answers

I believe the correct answer from the choices listed above is option B. The term that refers to the time interval between the passage of successive wave crests would be wave period. It is the time for a particle on a medium to make one complete vibrational cycle.

Bode's Law: correctly predicted the location of Jupiter, uses a number sequence to determine planetary distances, incorrectly predicted the location of Uranus and Neptune, all of the above

Answers

The correct answer for the question that is being presented above is this one: "correctly predicted the location of Jupiter, uses a number sequence to determine planetary distances." Bode's law correctly predicted the location of Jupiter, uses a number sequence to determine planetary distances.

Final answer:

Bode's Law, also known as Titius-Bode law, provides a numerical pattern that predicts the position of most planets in our Solar System, including Jupiter. It, however, fails to accurately predict the location of Uranus and Neptune. The fundamental principles of planetary motion were established by Kepler's laws and later consolidated by Newton in his Universal Law of Gravitation.

Explanation:

This question pertains to Bode's Law, a rule of planetary distances at times referred to as the Titius-Bode Law. The rule indicates a pattern of increasing distances of the planets from the sun, which interestingly correlates to the position of most planets in our Solar System, including Jupiter. However, exceptions, particularly Uranus and Neptune, don't fit precisely into this pattern.

The origins of planetary motions can be traced back to the work of scientists like Herr Tycho Brahe, Johannes Kepler, and Sir Isaac Newton. Kepler's work in particular developed three fundamental laws of planetary motion using Brahe's meticulously collected data. These laws describe the behavior of planets in their orbits and together provide the foundation of the Universal Law of Gravitation as later synthesized by Newton.

If there are 50 grams of U-238 on day zero of radioactive decay, how much will there be after 4.5 billion years

Answers

We use the formula of the half-life to calculate for the remaining U-238 after 4.5 billion years. The formula is expressed as A = A₀ (1/2)^(t/h) where A is the final amount, A₀ is the initial amount of the substance, t is the time and h is the half-life of the substance wherein for U-238 h is equal to 4.47 billion years.

A = A₀ (1/2)^(t/h)
A = 50 (1/2)^(4.5 / 4.47)
A = 24.88 g

Any force that causes an object to move in a circle is called a(n)a. balanced force.
b. unbalanced force.
c. gravitational force.
d. centripetal force.

Answers

a). balanced force
b). unbalanced force
There's no such thing as either of these. A group of two or more forces can be balanced or unbalanced. A single force can't be.

c). gravitational force ... doesn't cause an object to move in a circle;
   Drop a stone from the roof of a tall building and watch it fall.
   It goes straight down, not in a circle.

d). centripetal force ... force directed toward the center of a circle,
   causes an object to move in a circle.
