Answer: A) It has the same types of atoms on both sides of the reaction
arrow.
Explanation: A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow.
The vessel must also have red and green side lights.
The red light is placed on the port (left) side of the boat while the green light is placed on the starboard (right) side of the vehicle. The white lights are on both the masthead (front) and stern (rear) of the boat, unless the vessel is less than 39.4 feet, in which case the front and rear white light may be combined as only one white light.
The answer to that question is TRUE just had that question last period lol
Explanation:
Following are two interactions that are generally involved when we use a TV remote control to change the channel :
1. Figure touches remote buttons, and its a short range interaction.
2. Now remote sends signal to Television, this is a long range interaction.
Answer:
a) 0 J
b) 0.92J
Explanation:
The work is defined as:
![W=F*d*cos(\theta)\\](https://tex.z-dn.net/?f=W%3DF%2Ad%2Acos%28%5Ctheta%29%5C%5C)
because the normal force is perpendicular to the displacement the work done for it is zero.
![W_N=F_N*d*cos(90)=0](https://tex.z-dn.net/?f=W_N%3DF_N%2Ad%2Acos%2890%29%3D0)
The force because of frictions has an angle of 180 degrees because it is opposite to the motion, so:
![W_f=F_f*d*cos(180)\\W_f=-\µ*F_N*d\\W_f=-0.30*1.7N*1.8m\\W_f=-0.92J](https://tex.z-dn.net/?f=W_f%3DF_f%2Ad%2Acos%28180%29%5C%5CW_f%3D-%5C%C2%B5%2AF_N%2Ad%5C%5CW_f%3D-0.30%2A1.7N%2A1.8m%5C%5CW_f%3D-0.92J)
