Not easily compressible
-Little free space between particles
Does not flow easy
-Particles cannot move past each other
Answer:
a. 600 ml, 12
Explanation:
The movement described in the question exhibits that of a polygon. Exhibiting a constant distance and angle with only varying direction until the starting point is reached.
The sum of exterior angles of a polygon = 360 degrees.
Exterior angle of a polygon = (360 ÷ number of sides)
Therefore,
Number of sides = 360 ÷ exterior angle
Exterior angle = 30 degrees
Hence,
Number of sides = 360 ÷ 30 = 12 sides
Since distance traveled of 50 miles is the same for each displacement ;
Total displacement = distance traveled * number of sides
Total displacement = 50 * 12 = 600 miles.
Answer:
1. When a cold air mass and a warm air mass meet but are at a standstill, the boundary is called stationary front.
2. If warm or more humid air presses forward and colder or drier air draws back, the boundary is called warm front.
3. If colder or drier air presses forward and warmer or more humid air draws back, the boundary is called cold front.
4. Sometimes a warm air mass can get caught between two cold fronts, which can force the warm air up into a wedge shape is called occluded front.
Answer:
The current can be controlled by modifying the resistance value
Explanation:
The current can be controlled by modifying the resistance value, usually a variable resistance device called potentiometer is used. This can be observed mathematically using the ohm law which is defined as voltage equal to the current product by resistance.
V = I*R
where:
I = current [amp]
R = resistance [ohm]
V = voltage [volt]
We can see that if we reduce the resistance the current will be increased
I = v / R
And if we amplify the resistance (R) the current will be diminished
The value of change in kinetic energy, ΔEk when a cart is being pulled forward by a hanging mass is Positive
In order words, ΔEk in the above question is positive
<h3>What is kinetic energy?</h3>
Kinetic energy can be defined as the energy a body possess when the body is in motion or due its motion
