C.0.4 kg
This is your answer!
Answer: intensity
Explanation:
b. family.
c. Both A and B
Answer: option C
Explanation:
A DUI (driving while under the influence of alcohol or drugs) conviction means that a person has been found guilty, of either DUI or has been found guilty of driving with a 0.8% or more blood alcohol concentration. If a person is found guilty, the DUI conviction will remain on record of driving for 75 years. A DUI conviction not only affects the driver and his/her personal relationships. Conviction can also lead to imprisonment, which will also have a negative effect on family and friends.
B. 1.28 m/s
C. 0.49 m/s
D. 3.1 m/s
Answer: 1.38 m/s to the right.
Explanation: We can solve this problem using the principle of conservation of momentum. The momentum of an object is defined as the product of its mass and velocity, and the total momentum of a closed system is conserved, meaning that the total momentum before a collision is equal to the total momentum after the collision.Let the initial velocity of the dart be v, and let the final velocity of the dart and the block be vf. The momentum of the dart before the collision is given by p = mv, where m is the mass of the dart. The momentum of the dart and block after the collision is given by (m + M)vf, where M is the mass of the block.Using the principle of conservation of momentum, we have:p = (m + M)vfSubstituting the given values, we get:0.012 kg v = (0.012 kg + 0.2 kg) 0.78 m/sSimplifying, we get:v = (0.212 kg) (0.78 m/s) / 0.012 kgv ≈ 1.38 m/sTherefore, the velocity of the dart just before it hits the block is approximately 1.38 m/s to the right.
Its 2.1, I just took the test, the verified answer is wrong.
