Answer:
option A
Explanation:
given,
shear force = 425 N
Shear modulus = 1.7 × 10⁹ N/m²
disk equivalent to solid cylinder
height = 0.7 cm and diameter = 6.50 cm
hence, the correct answer is option A
Explanation:
modern quantum mechanics explains these periodic trends in properties in terms of electron shells. the filling of each shell corresponds to a row in the table
I think the answer is D. permit the wave to travel through it
The formula for impulse is F*(t₂-t₁)=m*(v₂-v₁), where F is the force, t is time, m is mass and v is velocity.
In our case m*(v₂-v₁)=16 N s, m=4 kg, v₁=0 and t₁=0.
m*(v₂-0)=16 N s, we solve for v₂:
4*v₂= 16
v₂=16/4
v₂=4 m/s
So the final velocity of the ball is v₂=4 m/s.
Answer:
In physics, mass–energy equivalence is the principle that anything having mass has an equivalent amount of energy and vice ve
