I’m unsure whether there is a question there but in forces the force weight which includes gravity would be pushing the diver directly down. However if there was enough thrust from the diver the motion would change but ultimately will be accelerating downwards because of unbalanced forces
Answer:
Explanation:
According to Gauss's Law, the electric flux of a charged sphere is the electric field multiplied by the area of the spherical surface:
This is identical to the electric flux of a point charge located in the center of the sphere.
Answer:
Evidence for continental drift
Wegener knew that fossil plants and animals such as mesosaurs, a freshwater reptile found only South America and Africa during the Permian period, could be found on many continents. He also matched up rocks on either side of the Atlantic Ocean like puzzle pieces.
Explanation:
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.
