Answer:
(a). The time constant of the circuit is 2.17.
(b). The potential difference across the capacitor at t=17.0 s is 0.0396 V.
Explanation:
Given that,
Initial potential difference = 100 V
Potential difference across the capacitor = 1.00 V
(a). We need to calculate the time constant of the circuit
Using formula of potential difference
Put the value into the formula
On taking ln
(b). We need to calculate the potential difference across the capacitor at t=17.0 s
Using formula again
Hence, (a). The time constant of the circuit is 2.17.
(b). The potential difference across the capacitor at t=17.0 s is 0.0396 V.
Answer:
Copernicus discoveres thr heliocentric theory. It was previously believed that everything orbited the Earth, geocentric theory. Copernicus said he believed the Earth and everything else orbited around the Sun.
Answer:
A.Gravity acts to pull the object down
D.The object’s inertia carries it forward.
E.The path of the object is curved.
Explanation:
The motion of a projectile consists of two independent motions:
- A uniform motion along the horizontal direction, with constant horizontal speed
- A vertical motion with constant acceleration of g = 9.8 m/s^2 downward (acceleration due to gravity), due to the presence of the force of gravity, so the vertical velocity changes (increases in the downward direction)
As a result, the combined motion of the projectile has a curved trajectory (parabolic, more specifically). So the following options are correct:
A.Gravity acts to pull the object down --> gravity acts along the vertical direction
D.The object’s inertia carries it forward. --> there are no forces acting along the horizontal direction (if we neglect air resistance), so the horizontal motion continues with constant speed
E.The path of the object is curved
