Answer:
x = 541 m
Dt = ?
vi = 12 m/s
vf = 0 (stop)
a = ?
Use vf^2 = vi^2 + 2a(Dx): 0^2 = (12 m/s)^2 + 2a(541 m), a = -144 m^2/s^2, a = -144 m^2/s^2/(1082 m) = -.1331 m/s/s or -.13 m/s/s
Answer: resistance = 220 ohms
Explanation: given that
Power P = 55W
Current I = 0.5A
Potential difference V = 110V,
Using the formula
P = IV =V^2/R
55 = 110^2/R
R = 12100/ 55
R = 220 ohms
There is many activities you can do like running, sit-ups, push-ups, and squats.
Answer:
I think the answer is As you increase the current the resistance increases too.
Answer:
Explain that an investigation is observing or studying the natural world, without interference or manipulation, and an experiment is an investigation that involves variables (independent/manipulated and dependent/ outcome) and establishes cause-and-effect relationships (Schwartz, 2007).
