What is the density of a block of wood, that weigh 18 grams, and volume is 56ml

The resultant of the four forces on the balloon is 1,212.35 N at 62⁰.

The given parameters;

The resultant vertical force is calculated as follows;

[tex]F_y = 5120 \ N - 4050 \ N\\\\F_y = 1,070 \ N[/tex]

The resultant horizontal force is calculated as follows;

[tex]F_x = 1520 \ N - \ 950 \ N\\\\F_x = 570 \ N[/tex]

The resultant of the four forces is calculated as follows;

[tex]F = \sqrt{F_y^2 + F_x^2} \\\\F = \sqrt{(1,070)^2 + (570)^2} \\\\F = 1,212.35 \ N[/tex]

The direction of the force is calculated as follows;

[tex]\theta = tan^{-1} (\frac{1070}{570} )\\\\\theta = 62^0[/tex]

Thus, the resultant of the four forces on the balloon is 1,212.35 N at 62⁰.

Answer:

Repeatability is how much variability in the measurement system is caused by the measurement device. Reproducibility is how much variability in the measurement system is caused by differences between operators.

According to Newtonʼs Second Law of Motion:

F net = m  x  a

or

a = F net / m

Acceleration = net Force/ Mass = 161 / 70 = 2.3 m/s^2  [W]

If a 70 kg skater is acted upon by an unbalanced force of 161 N [West], his acceleration would be 2.30  m/s² towards the west

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

The mathematical expression for Newton's second law is as follows

F = m*a

where F represents the force applied

m is the mass of the object

a is the acceleration of the object

As given in the problem If a 70 kg. skater acted upon by an unbalanced force of 161 N

F =ma

By substituting the values of the force and the mass as 161 N and 70 kg respectively

161 N = 70×a

a= 2.30 m/s²

Thus, If a 70 kg skater is acted upon by an unbalanced force of 161 N, his acceleration would be 2.30  m/s² towards the west

Answer:

An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not.

Explanation:

Explanation:

TRUE - Two colliding objects will exert equal forces upon each other. If the objects have different masses, then these equal forces will produce different accelerations. ... FALSE - In any collision, the colliding objects exert equal and opposite forces upon each other as the result of the collision interaction.
