Answer:
A. Gravitational force
C. Their charges
Explanation:
As we'll discuss in this lesson, he found that the force between charged particles was dependent on only two factors: the distance between the particles and the amount of electric charge that they carried.
Hope it help you
have a good day :)
<u>Answer:</u>
<em>The chemical reactions involves changes in energy due to the changes in the breaking and building of bonds.</em>
<u>Explanation:</u>
The changes in energy that chemical reactions involves are:
- <em>Endothermic(absorbing) chemical reactions.</em>
- <em>Exothermic(releasing) chemical reactions. </em>
Endothermic: The chemical reactions which absorbs the energy those chemical reactions are called endothermic chemical reactions.
Exothermic: The chemical reactions which releases the energy those chemical reactions are called exothermic chemical reactions.
The similarity in the reactions is both reactions are related to the change in energy. In one reaction the energy is absorbing and in another reaction the energy is releasing.
Answer:
The displacement of the car is 10 km at an angle of 36.9 degrees.
Explanation:
(AP) A car travels 8.00 km west from A to B; then the car travels 6.0 km north from B to C. Calculate the total displacement of the car? to. 10 km 36.9 ° b. 10 km 34.8 ° c. 12 km 34.8 ° d. 12 km 34.8 ° e. 12 km 35.9 °
It is given that,
A car travels 8.00 km west from A to B
The car travels 6.0 km north from B to C
We need to find the total displacement of the car. Initially, the car is moving due west and then it moves due north. So, the displacement of the car is given by :
![d=\sqrt{8^2+6^2} =10\ km](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B8%5E2%2B6%5E2%7D%20%3D10%5C%20km)
To find angle,
![\tan\theta=\dfrac{6}{8}\\\\\theta=\tan^{-1}(0.75)\\\\\theta=36.86^{\circ}\\\\\theta=36.9^{\circ}](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%5Cdfrac%7B6%7D%7B8%7D%5C%5C%5C%5C%5Ctheta%3D%5Ctan%5E%7B-1%7D%280.75%29%5C%5C%5C%5C%5Ctheta%3D36.86%5E%7B%5Ccirc%7D%5C%5C%5C%5C%5Ctheta%3D36.9%5E%7B%5Ccirc%7D)
So, the displacement of the car is 10 km at an angle of 36.9 degrees.
Answer:
Explanation:
Given that
Distance from the center ,r= 0.1 m
The angular speed ,ω = 15.5 rad/s
We know that centripetal acceleration is given as
a=ω² r
a=Acceleration
r=Radius
ω=angular speed
a=ω² r
Now by putting the values in the above equation we get
![a=15.5^2\times 0.1\ m/s^2](https://tex.z-dn.net/?f=a%3D15.5%5E2%5Ctimes%200.1%5C%20m%2Fs%5E2)
![a=24.025\ m/s^2](https://tex.z-dn.net/?f=a%3D24.025%5C%20m%2Fs%5E2)
Therefore the acceleration of the clay will be
.
A cardiac pacemaker can be affected by a static magnetic field as small as 1. 7 mt. pacemaker wearer comes to a long, straight wire carrying 28 amperes.
A pacemaker is a device that regulates an unsteady heartbeat. A pacemaker is inserted into one or more cardiac chambers using flexible, insulated wires called leads. The electrical pulses needed to change the heart rate are delivered by these lines. Some of the most recent pacemakers don't need leads.
The risk of problems is often quite low while having a pacemaker put. The primary worry is that the pacemaker will no longer be able to regulate the heartbeat due to a malfunction or a wire that has moved out of place. The average patient lived 101.9 months (or 8.5 years) after having a pacemaker implanted; at 5, 10, 15, and 20 years later, 65.6%, 44.8%, 30.8%, and 21.4% of patients were still living, respectively.
