Explanation:
frequency = 1 wave/10s = 0.1 Hz
wavelength = 5.8 m
speed = wavelength × frequency
= (5.8 m)(0.1 Hz)
= 0.58 m/s
Answer:
Genetic modification or GMOs can change foods. It's typically used to preserve foods, enlargen foods or create seedless grapes
Explanation:
Answer:
Exothermic reaction for the HCl, endothermic reaction for the water
Explanation:
Heat was lost by HCl as its temperature lowered, so it was an exothermic reaction for the HCL.
Heat was gained by water as its temperature increased, so it was an endothermic reaction for the water.
m = Mass of water = 100 g
c = Specific heat of water =
= Change in temperature of water =
Heat is given by
Heat gained by water is .
Answer:
Density = 11.294g/cm³
Explanation:
Mass of the ball (m) = 5.910g
Diameter of the ball = 10.0mm
Radius r = 10.0/2 =5.0mm = 0.5cm
Volume of a sphere V = (4pr3)/3
V = 4*3.14*(0.5*0.5*0.5)/3 = V =1.570/3
V = 0.5233cm³
V = 0.5233cm³
Density = mass/volume
Density = 5.910/0.5233
Density = 11.2937g/cm³
Density = 11.294g/cm³
