Answer:
The mass of the gold bar is 1,544 g
Explanation:
Velocity is the vector,
made up of the scalar speed + direction of speed
b). Displacement is the vector,
made up of the scalar distance + direction of distance
Explanation:
You are given the initial velocity, the displacement, and the acceleration. You're looking for the final velocity. So you use the equation:
v² = v₀² + 2aΔy
When you solve for v, you take the square root. Your calculator will return a positive answer, but there are actually two possible answers: positive and negative.
v = ±√(v₀² + 2aΔy)
You must use the physical context of the problem. If we take up to be the positive direction, then v must be negative, since the projectile is moving down.
Answer:
D) The rubber object will become negatively charged, and the glass object will become positively charged.
Explanation:
Electron affinity of rubber or glass will decide the thing that rubber will get the negative charge or the glass will get the negative charge
As we know that if the electron affinity of a given material is high then that material will not lose its electron while rubbing with some other material.
When we compare rubber and glass then we know that electron affinity of rubber is more as compare to glass.
So rubber will get negative charge when we rub it with glass
so correct answer will be
D) The rubber object will become negatively charged, and the glass object will become positively charged.
D. Dyspareunia
I would say d because dyspareunia means painful sex so endometriosis, cyst, pelvic infections, and allergic reactions can all cause this.
