Answer:
Independent variable: amount of sugar
Dependent variable: size of the loaf of bread
Explanation:
The amount of sugar the mother adds is completely up to her, and the size of the loaf changes according to that, which is why the loaf size is the dependent variable
Answer:
Explanation:
A ) Distance between two adjacent anti-node will be equal to distance between two adjacent nodes . So the required distance is 15 cm .
B ) wave-length, amplitude, and speed of the two traveling waves that form this pattern are as follows
wave length = same as wave length of wave pattern formed. so it is 30 cm
amplitude = 1/2 the amplitude of wave pattern formed so it is .850 / 2 = .425 cm
Speed = frequency x wavelength ( frequency = 1 / time period )
= 1 / .075) x 30 cm
400 cm / m
C ) maximum speed
= ω A
= (2π / T) x A
= 2 X 3.14 x .85 / .075 cm / s
= 71.17 cm / s
minimum speed is zero.
D ) The shortest distance along the string between a node and an antinode
= Wavelength / 4
= 30 / 4
= 7.5 cm
Answer:
The equation for acceleration can be rewritten as B to calculate the net force acting on an object when its mass and acceleration are known.
Explanation:
I hope that helps! (B is the answer)
Density = (mass) / (volume)
= (50.4) / (57.9) = 0.87 gm/cm³
Since the density is less than 1.0, the paraffin floats in water.
Since it's so close to 1.0 on the low side, the paraffin floats
with most of it under the water line.
Answer:
How does energy travel?
One way the energy can travel is through radiation. An object can radiate energy in the form of electromagnetic waves, for example when a strong light is turned on and you can feel some heat coming from it, or when you walk under the sunlight and you can feel the heat in your skin.
Where is the initial source of energy in our solar system?
In the solar system, the source of energy comes from the Sun, and the sun irradiates that energy to all the nearby objects.
What is the process that gives off energy from the sun called?
The process is called radiation, this is all the energy that comes from the sun in the form of different electromagnetic waves (light in the visible range, UV rays, etc...)
