Answer:
c. 43 m/s
Explanation:
Given the following data;
Displacement, S = 90 meters
Time, t = 5.55 seconds
To find the initial velocity;
We would use the second equation of motion given by the formula;
Where;
- S represents the displacement or height measured in meters.
- u represents the initial velocity measured in meters per seconds.
- t represents the time measured in seconds.
- a represents acceleration measured in meters per seconds square.
We know that acceleration due to gravity is -9.8m/s² because the direction is downward.
Substituting into the equation, we have;
Rearranging the equation, we have;
Initial velocity, u = 43.41 ≈ 41 m/s
Answer:
infinity
Explanation:
Given that
Resistance = R
Resistivity = ρ
Length = L
Diameter = d
The resistance of wire R given as
A=Area
Now by putting the value of A
When d tends to infinity then d² will also tends to infinity.
So when d tends to zero then the resistance tends to infinity.
Therefore answer is ---
infinity
Direction from A to B divided by time(30s)
Answer:
True
Explanation:
Magnitude is the "value" the greater the value the greater the force is and vice versa
Answer:
Explanation:
Magma heats nearby rocks and underground aquifers. Hot water can be released through geysers, hot springs, steam vents, underwater hydrothermal vents, and mud pots. These are all sources of geothermal energy. Their heat can be captured and used directly for heat, or their steam can be used to generate electricity.
