The most destructive and fastest mass wasting is the rock slide. due to enormous size of rocks that will fall, its velocity will be great and its destructive potential is also very great. rock slide is very dangerous because it can happen anytime in slope parts
Yes, you can. Forces are vector quantities. It depends on the direction of your motion. The gravitational force only acts on the vertical direction component. However, you would still have to incorporate the forces both in the horizontal and vertical motion to determine the net force.
Answer: Fill the cup with water
Add a handle to the cup
Lift the cup over the counter.
Explanation:
The options given are:
- Slide the cup away from the edge
- Fill the cup with water
- Turn the cup upside down
- Add a handle to the cup
- Move the cup to the floor
- Lift the cup over the counter
Potential energy refers to the energy that's being stored in a particular object. The formula for potential energy is given as:
PE = mgh
where,
m = mass
g = gravitational field.
h = height
The actions that'll increase the potential energy of the cup that's placed on the kitchen counter will be:
1. Fill the cup with water - This increases the weight of the cup.
2. Add a handle to the cup - The mass is increased as well.
3. Lift the cup over the counter - The height is increased.
Answer:
greatest height=48.05 m
Explanation:
Applying motion equations,
upward motion (g= -10m/s2)
where
u = initial velocity
v = final velocity
g = gravitational acceleration
s = distance
2)when the rock is at the highest point the velocity = 0
total high to the highest point = 18.05 +30
= 48.05 m
Rutherford has discovered the nucleus (and it was quite small), which is full of protons and neutrons, and the outside of the nucleus were electrons (he did this by bombarding gold foil with alpha particles. This is a big step closer to the modern atomic model as well.
