Answer:
0.095 A
Explanation:
= Impedance of the RC series circuit = 525 ohm
= Operating voltage of the circuit = 50 Volts
= circuit current
According to ohm's law
Inserting the values
Since this a position vs time graph, the velocity will be the slope of the line.
(5-3) / (3-0)
2/3 m/s
.6666 m/s

I don't know what this is. I haven't done this yet
Answer:
2 s, -20 m/s
Explanation:
Given:
y₀ = 20 m
y = 0 m
v₀ = 0 m/s
a = -9.8 m/s²
Find: t and v
y = y₀ + v₀ t + ½ at²
0 = 20 + 0 + ½ (-9.8) t²
0 = 20 − 4.9 t²
t ≈ 2 s
v² = v₀² + 2a(y − y₀)
v² = 0 + 2(-9.8)(0 − 20)
v ≈ ±20 m/s
Since the rock is falling, v = -20 m/s.
Answer:
TRUE
Explanation:
BECAUSE AN OBJECTS DENSITY SHOWS HOW MUCH WEIGHT IS PER CUBIC UNIT. LIKE SAD HAS MORE DENSITY THAN WATER SO IT SINKS WHILE WOOD HAS LESS DENSITY THAN WATER SO IT FLOATS
