1) An electron is moving east in a uniform electric field of 1.53N/C directed to the west. At point A, the velocity of the electron is 4.51�105m/s pointed toward the east. What is the speed of the electron when it reaches point B, which is a distance of 0.400m east of point A? 2) A proton is moving in the uniform electric field of part A. At point A, the velocity

You ride your bike north for 100 m at a constant speed of 5 m/Your acceleration is…
inessss [21]

Answer:

our acceleration is 0 because there is a constant speed..

a = final speed - initial speed / time

final speed = initial speed ( since speed is constant)

therefore acceleration is 0

Two canoeists in identical canoes exert the same effort paddling and hence maintain the same speed relative to the water. One pa
Serga [27]

Answer:

Speed of river is 0.45 m/s

Speed of boat is 2.65 m/s

Explanation:

v_r = Speed of river

v_c = Speed of canoe

v_r+v_c=2.8\ m/s

v_r-v_c=-1.9\ m/s

Adding the equations we get

2v_r=0.9\\\Rightarrow v_r=\frac{0.9}{2}\\\Rightarrow v_r=0.45\ m/s

0.42+v_c=2.8\ m/s\\\Rightarrow v_c=2.8-0.45\\\Rightarrow v_c=2.65\ m/s

Speed of river is 0.45 m/s

Speed of boat is 2.65 m/s

The following forces act on an object: 10 N north, 7 N south, and 4 N east. What is the magnitude of the net force?
spin [16.1K]

Given data;

 Fn = 10 N

 Fs = 7 N

 Fe = 4 N

           force in X direction (Fx) = 4 N

           force in Y direction (Fy) = 10-7 = 3 N

           Net force (Fnet) = Sq.root[(Fx)² + (Fy)²]

                                      = Sq root [ 4² + 3² ]

                                      = 25 N

        <em> Net force acting = 25 N</em>

How does gay-lussac's law apply to everyday life?
vladimir2022 [97]
Gay-Lussac's Law shows the direct relationship between pressure and temperature for an ideal gas with constant volume. Mathematically it is
\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}} 

This particular has a lot of application in our everyday life. In cooking, for example, we apply this concept when using a pressure cooker. We increase/decrease the temperature to meet the right amount of pressure.
 
In addition, knowing that pressure increases when temperature does can help you with road safety. Knowing that temperature affects heat directly, we must be careful in making sure that tires are not overheated or else they explode out of too much pressure inside.
