Answer:
(3) 4.62 ohms
Explanation:
Te equivalent resistance R is gotten from
1/R = 1/R₁ + 1/R₂ + 1/R₃ where R₁ = 10.0 ohm, R₂ = 15.0 ohm and R₃ = 20.0 ohm
1/R = 1/10 + 1/15 + 1/20
1/R = 0.1 + 0.0667 + 0.05
1/R = 0.2167
R = 1/0.2167
R = 4.62 ohms
Wavelength = (speed) / (frequency)
The speeds of the two possible signals are equal, just like
all other forms of electromagnetic radiation.
Wavelength of 895 MHz = (3 x 10⁸ m/s) / (8.95 x 10⁸/s) = 0.335 m
Wavelength of 2560 MHz = (3 x 10⁸ m/s) / (2.56 x 10⁹/s) = 0.117 m
The price of apples has jobs but non-zero not buy anymore because she has enough to what of 1
The specific gravity is how the density of the object compares to the density of water. Water's density is 1gram per milliliter. We just need to figure out the density of the object.
The object is .8 kg and it displaces 500mL of water, so the density is the mass divided by the volume. Since the density of water is given in grams, we have to convert the objects mass from kg to g and then we can get the density.
.8kg * 1000g/kg = 800 grams
So
800g/500ml = 1.6grams/mL this is the density.
So divide the density of your object by the density of water, which is 1g/mL, you get 1.6 as the specific gravity. This means the object is 1.6 times more dense than water.
Answer:
A) 9000 Joules
B) 450 Watts
Explanation:
Work equals change in energy:
W = ΔPE
W = mgΔh
W = (600 N) (15 m)
W = 9000 J
Power is work per time:
P = W/t
P = (9000 J) / (20 s)
P = 450 W
