Answer:
45.1 m/s
Explanation:
use the equation v = u + at
substitute the values v = 0 + 9.8×4.6
v = 45.08
round to 3 s.f v = 45.1 m/s
Answer:
Motion may be divided into three basic types — translational, rotational, and oscillatory.
Explanation:
The correct answer is (B) The force on A is exactly equal to the force on B. Two tiny beads are 25 cm apart with no other charges or fields present. Bead A carries 10 µC of charge and bead B carries 1 µC. The statement that<span> is true about the magnitudes of the electric forces on these beads is the force on A is exactly equal to B.</span>
Answer:
E = 44 kV / m
Explanation:
In a capacitor the potential difference is
ΔV = -E x
E = - ΔV / x
Let's reduce to the SI system
x = 0.5 mm = 0.5 10⁻³ m
Let's calculate
E = 22 / 0.5 10⁻³
E = 44 10³ V / m
E = 44 kV / m
Note that this electric field is uniform
