Answer:
The gplanet is 0.193 m/s^2
Explanation:
The speed of the pulse is:
where
m=mass of the wire=4 g= 4x10^-3 kg
M=mass of the object= 3 kg
Replacing values:
Wavelength and frequency are important because every frequency has its place on the electromagnetic spectrum. Also electromagnetic spectrum has many different wavelengths and frequencies on it . We only see a small fraction of what is created. The wavelength and frequency differs from wave to wave. You go from the lower frequency microwaves all the way up to the high frequency of gamma rays. It is important to determine the "type" of light because different wavelengths have different pulsation speed. The gamma rays pulse much faster then the light we see, and the light we see also goes faster than microwaves.
Answer:
Explanation:
The resulting valie would be too large
They are called stem cells. This cells are undifferentiated which means it can specialize in other types when it receives the right stimuli. They can divide through mitoses and become more stem cell or become a bone, muscle, blood cell, etc.
They can have 2 origins: embryos or some human tissue; their function is to regenerate or substitute damaged cells
Answer:
7.72 Liters
Explanation:
normal body temperature = T_body =37° C
temperature of ice water = T_ice =0°c
specfic heat of water = c_{water} =4186J/kg.°C
if the person drink 1 liter of cold water mass of water is = m = 1.0kg
heat lost by body is Qwater =mc_{water} ΔT
= mc{water} ( T_ice - T_body)
= 1.0×4186× (0 -37)
= -154.882 ×10^3 J
here negative sign indicates the energy lost by body in metabolic process energy expended due to brisk - hour long walk is Q_{walk} = 286 kilocalories
= 286×4186J
so number of liters of ice water have to drink is
n×Q_{water} =Q_{walk} n= Q_{walk}/ Q_{water}
= 286×4186J/154.882×10^3 J
= 7.72 Liters
