Answer:
3. less than the kinetic energy of thesilly putty before the collision.
Explanation:
This is because kinetic energy is dependent on the mass and velocity of an object. Mathematically, it is given as:
K. E. = ½*m*v²
Where m = mass
v = velocity
In the case of the silly putty, we know that the masses of the ball of silly putty and the bowling ball are conserved, hence, the kinetic energy depends solely on the velocity at which the object moves.
After the collision with the bowling ball, because of how heavy a bowling ball is, the speed of the silly putty and bowling ball will definitely be less than the speed of the silly putty before collision, i. e. u > v.
Hence, the kinetic energy after collision will be less than the kinetic energy before collision.
The observation point on Earth and the two stars form a triangle. The two sides of the triangle are 23.3 ly and 34.76 ly and their included angle is 76.04°. We can use the cos rule to find the third side, which is the distance between the two stars.
c² = a² + b² - 2abCos(C)
c² = (23.3)² + (34.76)² - 2(23.3)(34.76)Cos(76.04)
c = 36.88 light years.
I believe the answer would be lungs
B because 2800 divide by 40 is 20
