the answer for this is touch or texture
Answer:
All the three quantities will have non zero joules.
Explanation:
At the initial position of rest the system will have only gravitational potential energy while the other 2 quantities will be zero.
when the system reaches a height (y-h) only kinetic energy will be zero while the other 2 quantities will be non zero
At the position of (y-h/2) all the 3 quantities will be non zero.
Answer:
option (a)
Explanation:
Wire 1:
length = 2L
Area = 2 A
Wire 2: length = L
Area = A
As we know that the resistance of a wire is directly proportional to the length of the wire and inversely proportional to the area of crossection of the wire.
Let ρ be the resistivity of the cooper wire.
Resistance of wire 1
R1 = ρ x 2L / 2 A = ρ L / A
Resistance of wire 2:
R2 = ρ x L / A = ρ L / A
As R1 = R2
It means both the wires have same resistance.
Answer:
P waves are a type of seismic wave that is characterized by being a longitudinal mechanical wave, which means that the medium through which they travel is alternately compressed and dilated in the<u> same direction of propagation</u>. This means they propagate in a similar way to the sound.
These waves are faster than the S waves, so when an earthquake occurs these waves <u>are the first to be recorded by the seismograph</u>. They can also travel through any type of material (solid, liquid or gaseous), this means they are able to <u>travel through solid rocks as well as in oceans or volcanic magma and are even able to be </u><u>transmitted through the atmosphere</u>, that is why they are sometimes perceived by people and animals as a deep sound.
The y component of the vector is 37.7 N and the angle between the vectors is 26.2⁰.
<h3>Y-component of the vector</h3>
The y component of the vector will be determined from the resultant vector and the x component of the vector.
R² = Y² + X²
Y² = R² - X²
Where;
- Y is the y-component of the vector
- X is the x component of the vector
- R is the resultant vector
Y² = 85.2² - 76.4²
Y² = 1,422.08
Y = √1,422.08
Y = 37.7 N
<h3>Angle between the vectors</h3>
θ = arc tan (Y/X)
θ = arc tan (37.7/76.4)
θ = 26.2⁰
Thus, the y component of the vector is 37.7 N and the angle between the vectors is 26.2⁰.
