What happens to frequency of a wave if speed is doubled?
The frequency also doubles of the wave length stays the same. Remember that Velocity = (the wavelength) x (the frequency)
What happens to the volume of a cone when the radius is doubled?
The volume is added by the variable "x" and multiplied by pi
What happens to the volume of a box when the length and width are the same?
The formulae stays the same. Length x Width x Height. So for example if the length was 4cm, the height was 3cm and the width was 4cm. Then, the volume would be 4x3x4= 48cm3
If y is proportional to the square of x fully explain what happens when x is doubled?
Example with numbers: Y = X2 Y = (2)2 Y = 4 ==== So if Y is ( directly ) proportional to X2 when X is doubled Y is increased four times.
In a direct variation if the x value is doubled is the y value doubled?
it is doubled
What happens to frequency of a wave if speed is doubled?
The frequency also doubles of the wave length stays the same. Remember that Velocity = (the wavelength) x (the frequency)
What happens to the wavelength of a wave wen the frequency of the wave is doubled but the wave speed stays the same?
speed = freq. X wavelength Hence frequency and wavelength are inversely related when the speed is same. So if the frequency is doubled, then wavelength becomes half of the initial length.
How could you keep an object acceleration the same if the force acting on the object were doubled?
By halving the mass. F = M A if F is doubled and A stays the same, in order for both sides to remain equal.. 2F = xM A x = .5
What happens to the wavelenght of a wave when the frequencey of the wave doubled but speed stays same?
Speed = wavelength x frequency, so wavelength = speed / frequency. Therefore, the wavelength is inversely proportional to the frequency. Double the frequency means half the wavelength.
What happens to the area of a circle when its doubled?
When the diameter is doubled, perhaps? Then the area is 4 x larger.
Voltage across resistor is doubled the current is?
Ohm's law states that the voltage across a resistor is the product of the current times the Resistance or V=I x R (I times R). V is Voltage, R is Resistance, and I is Current or Amperage. So if the Voltage is doubled and Resistance stays the same, the Current will be doubled.
Will the value of the expression 20- x increase decrease or stay the same as x Explain?
If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.
What happens when you multiply a negative number by 1?
The negative number multiplied by one, the answer stays the same. for example -52 x 1 = -52
What happens to the volume of a cone when the radius is doubled?
The volume is added by the variable "x" and multiplied by pi
What happens to the circumference of a circle if youndouble the radius?
Circumference = 2 x π x radius double radius: new_circumference = 2 x π x (radius x 2) = (2 x π x radius) x 2 = circumference x 2 → if the radius is doubled, the circumference is doubled.
Why does 38 x 50 have the same answer as 76 x 25?
<><>Because one number in each is doubled
What happens to the volume of a box when the length and width are the same?
The formulae stays the same. Length x Width x Height. So for example if the length was 4cm, the height was 3cm and the width was 4cm. Then, the volume would be 4x3x4= 48cm3
