Answer:
1. and 2. If the buoyant force is greater than the object's weight, the object rises to the surface and floats. If the buoyant force is less than the object's weight, the object sinks. If the buoyant force equals the object's weight, the object can remain suspended at its present depth.
3. When the buoyant force equals one ton, it will sink no further. When any boat displaces a weight of water equal to its own weight, it floats. This is often called the “principle of flotation” where a floating object displaces a weight of fluid equal to its own weight.

Can anyone help me with my history question.
Its physical weathering and physical weathering can be sometimes called mechanical weathering it includes the processes which break rocks apart changing their chemical composition.
Answer:v=142.85 mph
Explanation:
Given
Distance between two cities is 1000 miles
Speed of plane 1 id 250 mph
Plane 1 leaves at 7 am and Plane 2 leaves at 7:30 am
They will collide if plane 2 travels 300 miles and Plane 1 travels 400 miles in t and t+0.5 hr respectively
Time taken by plane 2
----1
time taken by plane 1 to travel 400 miles
-----2
substitute value of t in 2
Answer:
<em>The amount of charge increases.</em>
<em></em>
Explanation:
For a capacitor that has its plates still connected to a battery, the voltage on the capacitor remains constant. If the distance between the two plates of this capacitor is decreased, the capacitance will increase, and then the charge on the plate will increase in accordance with the relationship
Q =CV
From this relationship, if V is held constant, then Q has to increase for C to increase also.
