Answer: 5.4 kg
Explanation:"Recall that force is the result when we multiply the values of an object's mass and acceleration. Mathematically, we have
F = ma
where F is the force (in Newtons, N), m is the mass (in kilograms, kg), and a is the acceleration (in m/s²).
Since we know that the eagle was accelerating at 22.35 m/s² with a force of 120N, we can solve for the eagle's mass as shown below.
m = F/a
m = (120)/(22.35) ≈ 5.4 kg
Hence, the eagle has a mass of approximately 5.4 kg."
Answer:
The value is
Explanation:
From the question we are told that
The number of students is
The metabolic rate for each student is
The time duration is
The molar specific heat of air is
The volume is
The pressure is
The initial temperature is
Generally the metabolic rate of the students is
=>
=>
The total heat generated by the students is
=>
=>
From the ideal gas law we can evaluate n (number of moles ) as
Here R is the gas constant with value
So
=>
Generally the heat generated is mathematically represented as
=>
=>
=>
=>
Answer:
4.9N
Explanation:
The formula for weight is F = ma.
You plug in the mass of 0.5kg and an acceleration of 9.8 to get
F = (0.5)(9.8)
F = 4.9N
Answer:
All objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.
Explanation:
Newton's Second Law, if I remember right.
Answer:
The cars would both move in the direction with the greatest momentum. We know the truck would have the greatest momentum due to having the greatest mass. Plus, factors which affects momentum are mass and velocity.
Thus, the car would move forward towards the direction of momentum of the truck. Both will continue to move at the same velocity.
E.g. truck hits the back of a stationary car, both will move forward, to the right & travelling at the same speed, but lower than the initial velocity of the truck. Now the total the total momentum before the collision is the same as the total momentum after the collision; as a result, momentum has been conserved.
Hope this helps!
