Answer:
Farm = 98.1 [N]
Explanation:
To solve this problem we must draw the respective free body diagram, with the forces acting on the monkey. An analysis of the sums on the y-axis must be performed, in this axis the weight is acting down and the forces of both arms pulling up.
Weight is defined as the product of mass by gravitational acceleration.
W = m*g
where:
m = mass = 20 [kg]
g = gravity acceleration = 9.81 [m/s²]
W = 196.2 [N] (units of Newtons)
As this force points down, the force of both arms must go up, therefore each arm exerts a force of:
Farm = 196.2 / 2
Farm = 98.1 [N]
B. Closed, because you can't call it isolated because your not isolating the jar, plus the jar is nether connected or opened. Hope that helps!
Fromula for calculating mass when density and volume are given is as m=ρV mass of blood = 1.05 × 2 mass of bag of blood = 2.15 kg
In order to keep the object moving in the same direction and with same speed, its initial and final momentum should be zero.
∴ Net force on the object should be zero.
Answer:
F = 0i (in the x-direction), 0j (in the y-direction),-8.59*10^-4 N k (In the z-direction)
Explanation:
The force given by charged particles moving in a magnetic field is given below (cross is cross product, they don't have that format in the equation tool):
![F=qv (cross) B\\](https://tex.z-dn.net/?f=F%3Dqv%20%28cross%29%20B%5C%5C)
Now we can perform the cross product between v and B

Now multiply by Q (charge) to get the force
![F = -1.24*10^-8 * 69300\\F = -8.59*10^-4N](https://tex.z-dn.net/?f=F%20%3D%20-1.24%2A10%5E-8%20%2A%2069300%5C%5CF%20%3D%20-8.59%2A10%5E-4N)
F = -8.59*10^-4 N k
F = 0i, 0j, (-8.59*10^-4)k
