Explanation:
1. =
* cos
⇒ 16*cos32 ≈ 13.6 m/s (13.56)
2. =
* sin
⇒ 16* sin32 ≈ 9.4 m/s
3. =
=
(the g (gravity) depends on the country but i'll take the average g which is 9.2m/s^2)
≈ 3.6677+1.5 ≈ 5.2m
4. =
=
≈ 23.5m (23.47)
5. -
answer 4 could be wrong, not certain about that one and i don't know 5
Answer:
(a) Current flowing through truck battery is 180 A
(b) Time taken in calculator is 333.33 s
Explanation:
(a) Given:
The charge on the truck battery,q = 720 C
Time, t = 4.00 s
Consider I be the current flowing through truck battery.
The relation between current, charge and time is:
I = q/t
Substitute the suitable values in the above equation.
I = 180 A
(b) Given:
The charge on the calculator,q = 7.00 C
The current flowing through calculator, I = 0.3 mA = 0.3 x 10⁻³ A
Consider t be the time.
The relation between current, charge and time is:
t = q/I
Substitute the suitable values in the above equation.
I = 333.33 s
