Answer:
7.07 hours
Explanation:
divide the distance by the speed
so in this case, divide 672 by 95
Answer:
Explanation:
Given a ball of mass m= 0.5kg
The ball moves in as circle of radius r= 0.4m
Speed of the ball is v = 4m/s
Centripetal force is exerted on ball and it is given as
Fc = m•ac
ac is centripetal acceleration and it is given as
ac = v²/r
Then,
Fc = mv²/r
Fc = 0.5 × 4²/0.4
Fc = 20N.
The force exerted on the ball is 20N
Answer:
Net force needed to accelerate the skier is 136 N
Explanation:
As per Newton's 2nd law we know that net force on the system is product of mass and its acceleration
here we know that
m = 34 kg
so we have
F = ma
Answer:
the different about the molecules we needed to make protein 3 compared to the molecules we used to make protein 2 is that if we used 2 molecules than it will be smaller than using protein 3.
