The answer is A. Proton. Protons have the opposite charge to electrons, which have negative charges.
Answer:
The density is
Explanation:
From the question we are told
The radius of the cylinder is
The length of the cylinder is
The density of the glucose is
The depth is
The net force on the string is
The net force on the string is mathematically represented as
Here is the force due to the weight of the cylinder
Which mathematically evaluated as
Where is the volume of liquid displaced which is equal to the volume of the cylinder which is mathematically represented as
=>
is the buoyant force acting on the cylinder due to the glucose
So substituting into formula for
Answer:
halved
Explanation:
The velocity of the a wave is obtained by multiplying the frequency and wavelength.
Where
v = Velocity
f = Frequency
= Wavelength
The velocity here is constant. So, if the frequency is doubled the wavelength is halved.
Answer:
A. How much matter an object has, plus the magnitude and direction of its motion
Explanation:
Momentum is defined as the product of mass by velocity, in the international system of measurements (SI) momentum has the following Units [kg*m/s].
P = m*v
where:
P = momentum Lineal [kg*m/s]
m = mass [kg]
v = velocity [m/s]
Therefore the answer is A) How much matter an object has, plus the magnitude and direction of its motion
When all of the objects are lifted to the same height, the object
that has the most mass also has the most potential energy.
If we knew anything about the masses of the objects in this question,
then we could be more specific.
Calculation:
<em>Potential energy = (mass) x (gravity) x (height above the reference level)</em>.
