The moment of inertia of the tetrahedron will be 435.75,Moment of inertia is found by the application of integration.

The sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation expresses a body's tendency to resist angular acceleration.

The moment of inertia  of a tetrahedron of constant density is found as;

[tex]\rm I_Z = \int\limits^a_b {dz} \, dv \\\\ dv=dxdy\\\\ I_Z = \int_0^9 \int_0^{8-\frac{8x}{9}} \int_0^{5-\frac{5x}{9} -\frac{5x}{8} }(x^2+y^2)dzdy[/tex]

After applying the limit, we get the answer is;

[tex]\rm I_Z= \frac{1743}{4} \\\\ I_Z= 435.75[/tex]

Hence, the moment of inertia of tetrahedron will be 435.75

The lifting force applied by the person in lowering the basket is determined as 7.8 N.

The lifting force applied by the person is determined from Newton's second law of motion.

F = mg - ma

F = m(g - a)

where;

F = 1(9.8 - 2)

F = 7.8 N

Thus, the lifting force applied by the person in lowering the basket is determined as 7.8 N.

Answer:

Push-ups. Let M1 be the mass of the body and M2 be the mass of weights. Assume that M1 must be heavier than M2. Since M1 is heavier, M1 requires more force, and therefore work to be applied, let F1=M1*g. To bring our body back up, we need a force bigger or equal (if already in motion) to F1.

Let F2 = M2*g

Since F1 has to be bigger than F2 due to mass, we can build an equation for energy. Let X be a displacement, which is equal in both situations. Constructing a change of energy equation we can see that work done to lift the body is greater:

W1=F1*x

W2=F2*x

Where W1 is the work of the hands-on body, and W2 is the work of lifting weights. W1 has to be larger than W2. Since more work in W1, more muscle will be needed to complete a repetition, but only assuming that M1 > M2.

If the forces on an object are greater than zero,the object will definitely in the motion. This concept in accordance with law of inertia.

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body.

Newton's law of inertia states that a body wants to continue its motion until the external force is not acted on it.

Hence, if the force is grater than zero, the body will be in motion.

Answer:

Answer:2nd question answer is 2.75Explanation:

Mass of ball is missing in your 1st question.

for 2nd question,

Small cart,

m1 = 1.25kg

u1 = 2.5m/sec

v1 = -0.94m/sec ( negative sign indicate opposite motion)

Large cart,

m2 = ?

u2 = 0 m/s

v2 = 1.56 m/sec

from conservation of linear momentum,

m1*u1 + m2* u2 = m1*v1 + m2*v2

1.25*2.5 + m2*0 = 1.25*-0.94 + m2*1.56

3.125 + 0 = -1.175 + 1.56*m2

3.125 + 1.175 = 1.56*m2

4.3 = 1.56*m2

m2 = 4.3/1.56

m2 = 2.75 kg

if they stuck together instead of bounced. then,

total mass of bodies (m)= m1+m2= 4kg

final velocity of bodies (v) = ?

From , conservation of linear momentum,

m1*u1 + m2* u2 = m*v

1.25*2.5 + 2.75*0 = 4*v

3.125 = 4*v

v = 3.125/4

v = 0.78125 m/ sec.

The large cart has a mass of 2.75kg. This can be identified from the law of conservation of momentum. Its unit is kg.s⁻¹/m.

Momentum is the quantity that describes the motion of the body. The momentum equals the product of mass and velocity. Momentum= Mass/velocity. It depends on the velocity as velocity changes momentum also changes.

The law of conservation of momentum states that the initial and final momentums are the same in the system. It shows that the momentum of the system remains constant, before and after the collision.

In an isolated system of two bodies acting on each other, total momentum remains constant in the absence of external forces. It can neither be created nor destroyed.

Law of conservation of momentum:

Total momentum before collision = Total momentum after the collision

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

From the givens,

Mass of small chair, m₁ = 1.25kg,

The initial speed of the small chair before the collision, u₁ = 2.5 m/s,

The final speed of the small chair after the collision, v₁  = - 0.94 m/s (negative sign opposite sign),

The initial speed of the large chair before the collision, u₂ = 0 (large chair is at rest before the collision),

The final speed of the large chair after the collision, v₂ =  1.56 m/s,

The mass of a large chair m₂ =?

From the conservation of momentum:

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

(1.25×2.5) + (m₂×0) = (1.25(-0.94) + (m₂×1.56)

3.125 + 0 = - 1.175 +( m₂×1.56)

3.125+1.175 = ( m₂×1.56)

4.3 / 1.56 = m₂

m₂ = 2.75kg

Hence, the mass of a large chair, m₂ = 2.75kg.

The change in the internal energy of a system is equal to the difference in energy transferred to or from the system as heat and work done.

Work done is the energy needed or supplied to perform any task.

The first law of thermodynamics gives the relation between the heat and work done.

The heat added to a system is divide into two. One portion adds up heat to increase the internal energy and the left heat is used to do work.

ΔQ = ΔU + W

ΔU = ΔQ -W
