It would be Mass and Time which would be the two fundamental units.
The answer would be Matter
Despite current has a magnitude and a direction, like vectors, it is a scalar because it doesn't obey laws of vector addition. For instance, if we consider a junction of
in a circuit, and two currents entering this junction, we know that the resultant current is just the algebraic sum of the two currents, not the vector sum, so it is not a vector quantity.
Answer:
4009.21658986 Hz
Explanation:
v = Speed of sound in air = 348 m/s
L = Length of tube = 2.17 cm
Fundamental frequency for a tube where one end is closed and the other end open is given by
The fundamental frequency of the canal is 4009.21658986 Hz
Answer:
In order to understand all three questions one must have knowledge of rotational and transitional motion.
Explanation:
a.
Both energies could be compared by means of their motion,as Ball it self rolling and also moving linearly therefore it has combination of linear and rotational kinetic energy in the mean while block of ice just have linear kinetic energy therefore Basketball have more kinetic energy
in case of Basket ball
in case of Ice
b.
For momentum it is obvious that for basketball their is angular momentum along with linear momentum.
P = m v in case of linear momentum while
L= I w in case of angular momentum where I have rotational inertia and w is the angular velocity
their is no angular momentum in case of an ice block because it was moving in linear motion.
c.
Due to the additional angular momentum conserved in the case of basketball so it has more energy conserved as compared to ice block therefore frictional effect and ramp sloping does not hurt much motion of basketball as compared to ice blocking.
