True the only way to emit ur proton is if there are ground electrical
Answer:
electric flux through the three side = 2.35 N m²/C
Explanation:
given,
equilateral triangle of base = 25 cm
electric field strength = 260 N/C
Area of triangle = 
= 
= 0.0271 m³
electric flux = E. A
= 260 × 0.0271
= 7.046 N m²/C
since, tetrahedron does not enclose any charge so, net flux through tetrahedron is zero.
electric flux through the three side = (electric flux through base)/3
= 
electric flux through the three side = 2.35 N m²/C
Answer:
A control variable in scientific experimentation is an experimental element which is constant and unchanged throughout the course of the investigation.
Explanation:

- Initial velocity,u = -2 m/s
- Final velocity,v = -10 m/s
- Time taken, t = 4 seconds

Find the acceleration ( a ) .

We know that,

Substituting the values in the above formula, we get




Hence,the acceleration of a body is -2 m/s².
