Answer:
Q=mc∆tita.
4780J= m × 2445J/kg/°C × 5.43°C
4780J= m× 13276.35J/kg
m= 0.36Kg
Speed - the rate of change of position.
<span>Speed = Distance / Time. </span>
<span>Common units utilized for speed are meters per second (m/s) or miles per hour (mi/h). </span>
<span>Velocity - the rate of change of position. </span>
<span>Velocity = Displacement / Time. </span>
<span>Common units utilized for velocity are meters per second (m/s) or miles per hour (mi/h). </span>
<span>The main difference between speed and velocity is that speed is a scalar quantity (does not depend on direction) whereas velocity is a vector quantity (which does depend on direction). </span>
<span>Acceleration - Change of velocity over time. </span>
<span>Force = Mass x Acceleration. </span>
<span>Acceleration = Force / Mass. </span>
<span>Common used units of acceleration are meters per second squared (m/s^2). </span>
<span>Hope that helped :)</span>
