Answer:
less than 27 m/s
Explanation:
The average speed would be total distance (10 + 10 = 20 miles = 32000 m) over total time
The time it takes you to drive the first 10 miles (16000 m) at 24m/s is
16000 / 24 = 666.67 s
The time it takes you to drive the 2nd 10 miles (16000 m) at 30 m/s is
16000 / 30 = 533.33 s
The average speed is
< 27 m/s
So your average speed is less than 27 m/s
Answer:
ΔT = 78.32 °C
Explanation:
Kinetic energy of bullet is K
K = mv²/2
= .004 * ( 200 m/s )²/2
= 80 J
Half of the heat E = 40 J
Now a per the equation of energy transferred ,
E = cm ΔT
c is the specific heat of latent, m is the mass and ΔT is the change in temperature.
ΔT = 40 / ( .0305 × 4186 × .004)
ΔT = 78.32 °C
The membership rose among the baptist and methodists.
This condition is called Galileo's Law of Inertia which states that all bodies accelerate at the smart rate , no matter what are their masses or size. Inertia is that tendency of matter to resist changes in its velocity. <span>Isaac Newton's first law of motion captures the concept of inertia. </span>
Electrostatic force arises due the charges at rest.In a isolated atom there is three fundamental particles called electron,proton and neutron.the electron is negatively charged,proton is positively charged and the neutron is neutral.
Generally the force between electron and proton is attractive,there will be also repulsion between proton and proton.due to the strong nuclear forces atom main its stability In an stable atom the the neutron to proton ratio lies between 1 to 1.42.if the number of neutrons are increased more,the stability will be hampered resulting the decrease in nuclear force also.
As neutron is neutral,there will be no change in the electrostatic forces as there is no increment of charge.but when the neutron number is increased at that time the binding energy per nucleon is decreased which in turn affects the nuclear force which is a short range force.the nucleus becomes heavy and unstable which undergoes decay.
one thing we have to remember also that the nuclear force is spin dependent .so the change in neutron number affects the strong nuclear force which is the reason for its decrement.
