I assume that in this item, we are asked to solve for the force exerted during the heartbeat. Force is the product of the mass and acceleration. To solve for the acceleration in this item, we divide the velocity by time.
a = 1 m/s / 0.2 s = 5 m/s²
Then, we multiply this by the mass (in kg)
F = (80 g / 1000 g/kg) x (5 m/s²)
= 0.4 kg m/s² = 0.4 J
Therefore, every hearbeat will take 0.4 J of force.
Kesav will Planting nitrogen-fixing crops, such as peas, in rotation with wheat crops can dramatically reduce the variability of farmers' income with a high-yield, high-protein harvest. ... Instead, they depend on the presence of nitrogen as ammonium or nitrate ions in the soil.
A I think that is how lightning works anyways
Balance improves
Balance is the ability to maintain a controlled body position during performance of task. Age appropriate balance and coordination allows the child to be involved in the sports participation with a reasonable degree of success as it helps the body fluid movement for physical skill performance. <em />With good balance and posture injury and fall can be prevented. This can also help maintain appropriate controlled body movement.
