Answer:
The result of force distributed over an area – Pressure = Force(in Newton's – N)/area (m 2 ) Pascal (Pa) – SI unit for Pressure – Named after.

Answer:
15.3 m/s
Explanation:
Radius of orbit= 6400+6300 = 12700 km
Circumference of orbit= 2*(22/7)*12700 =79796.45*10^3 m
Now,
Speed= Distance / Time
= 79796.45*10^3/(24*60*3600)
= 15.3 m/s
Answer:
<h2>option C </h2><h2>decreasing its thickness and increasing its temperature. </h2>
Explanation:
<h2>Resistance is directly proportional to length and temperature of the wire and inversely to area.</h2>
<h3>if you increase the temperature the resistance will increase.(resistance is directly proportional to temperature)</h3>
<h3>if you decrease its thickness (area) then the resistance will increase ( resistance is inversely proportional to area)</h3>
hope it helps:)
Explanation:
Using kinematics,
s = ut + 0.5at².
We have s = 35.0m, t = 0.50s, a = 2.80m/s².
Substitute in the variables, we have u = 69.3m/s.
This u is only the initial velocity at t1. To find the velocity at t0, we apply a different kinematics equation with different values:
We have t = 5.00s, a = 2.80m/s², v = 69.3m/s.
Using kinematics,
v = u + at.
Substitute in the variables, we have u = 55.3m/s.
Hence the car's initial velocity is 55.3m/s.
