Examples of physical properties include: color, shape, size, density, melting point, and boiling point.
Explanation:
The given data is as follows.
Electric field (E) = 
Charge (e) = 
C
Formula to calculate the magnitude of force is as follows.
F = qE
= 
= 
Therefore, we can conclude that magnitude of the force on a calcium ion with charge +e is .
Answer:
D. half as much
Explanation:
let m and M be the mass of the planets and r be the distance between them.
then: the force of attraction between them is given by,
F = G×m×M/(r^2)
if we keep one mass constant and double the other and also double the distance between them.
the force of attraction becomes:
F1 = 2G×m×M/[(2×r)^2]
= 2G×m×M/[4×(r)^2]
= (1/2)G×m×M/(r^2)
= 1/2×F
therefore, when you double one mass and keep the other mass constant and double the distance between the masses you decrease the force by a factor of 1/2.
Answer:
Explanation:
Given parameters:
Average speed = 3.5miles per second
Unknown:
Initial speed = ?
Average speed = ?
Final speed in the interval = ?
Solution:
Since the bicyclist started from rest and speeds up steadily, it is correct to assume that her starting or initial speed is 0m/s.
At a state of rest, a body has no speed.
Average speed is the sum total of the speed covered at each time interval. This value is given already to be 3.5miles per second.
Final speed is the speed before the bicycle halts. This speed will be the same as the average speed here which is 3.5miles per second.
Speed is the rate of change of distance with time.
Answer : National Aeronautics and Space Administration
Problem : What does N.A.S.A stand for?
Explanation: NASA astronaut Christina Koch is pictured during a spacewalk. NASA stands for National Aeronautics and Space Administration. NASA was started on October 1, 1958, as a part of the United States government. NASA is in charge of U.S. science and technology that has to do with airplanes or space.
Hopefully this helps you!
