Answer:
The magnitude of the net electric field is:
Explanation:
The electric field due to q1 is a vertical positive vector toward q1 (we will call it E1).
On the other hand, the electric field due to q2 is a horizontal positive vector toward q2(We will call it E2).
Knowing this, the <u>magnitude of the net electric</u> field will be the<u> E1 + E2. </u>
Let's find first E1 and E2.
The electric field equation is given by:
Where:
- k is the Coulomb constant (k = 9*10^{9} Nm²/C²)
- q1 is the first charge
- d1 is the distance from q1 to P
And E2 will be:
Finally, we need to use the Pythagoras theorem to find the magnitude of the net electric field.
I hope it helps you!
Answer:
The truck must travel by 95.16 km/h to stay beneath the airplane
Explanation:
Lets explain how to solve the problem
How fast must a truck travel to stay beneath an airplane that is moving
105 km/h at an angle of 25° to the ground
The truck moves a long the horizontal ground
The airplane moves 105 km/h at an angle 25° to the ground
The truck must moves with velocity equal the horizontal component
of the velocity of the airplane to stay beneath the airplane
The angle between the line represented the velocity of the airplane
and the ground is 25°
→ The horizontal component of the velocity = v cos(25)
→ The velocity of the airplane is 105 km/h
→ The horizontal component = 105 cos(25) = 95.16 km/h
The velocity of the truck = the horizontal component of the airplane
<em>The truck must travel by 95.16 km/h to stay beneath the airplane</em>
Answer:
galaxy is a group of stars held together by gravity
Answer:
Explanation:
The mass difference is
Δm = m2 - m1
56.936296 u - 56.935399 u
= 0.000897 u
The energy released by the electron-capture decay
E = Δmc²
( 0.000897 u) c² ( 931. 5 MeV /c²÷ 1 u)
= 0.8355555 MeV
Nuclear energy comes from the binding energy that is stored in the centre of an atom and holds it together. To release the energy, the atom has to be split into smaller atoms. This process is called fission. Answer is: false. Correct answer is nuclear energy.
