Answer:the friction increase

Explanation:

that's all i got

Answer:

H = 1/2 g t^2      no original vertical velocity

t = (2 * 2000 / 9.8)^1/2 = 20.2 s

Sx = 100 m/s * 20.2 s = 2020 m

A rescue pilot drops a survival kit while the plane is flying at an altitude of 2000 m then the distance travelled by the package after the drop will be 2020 meters.

A force that prevents two solid objects from smoothly sliding or rolling over one another is known as friction. While frictional forces, such as the traction required to walk without slipping, may be advantageous, they can provide a significant amount of resistance to motion. To overcome frictional forces in the moving parts, automotive engines use about 20% of their total power.

The main contributor to friction between metals appears to be adhesion, or the forces of attraction, between the contact regions of the surfaces, which are always microscopically uneven.

According to the question,

H = 1/2 g t²      

2000 = 1/2(9.8) t²

t² = 4000/ 9.8

t = 20.2 seconds.

So the distance travelled by the package will be :

Distance = s × t

Distance = 100 m/s × 20.2 s

Distance = 2020 meters.

Explanation:

Tonya has been working a lot and if she is not able to maintain her healthy then she will probably gain a little weight. Hence, option B is correct.

Diet, in the context of nutrition, refers to the items that a person frequently eats and drinks (or a group). A regulated diet, or one that satisfies a person's physical needs, may be used during a specific illness therapy or health condition management.

For instance, a diabetic's diet may be limited to a variety of foods and beverages that help control blood sugar levels. Numerous fiber, non-starchy fruits, and vegetables are included in the diet suggested for diabetic patients. Because starchy foods are high in carbohydrates, eating a lot of them could raise your blood sugar levels.

If Tonya has been working a lot and is not able to maintain healthy habits as she normally does then she will gain some weight. But she must make sure to start a healthy lifestyle as soon as possible because in a long run this habit can affect her health very badly.

The specific heat capacity of the metal of mass 770 g which required 155 calories to raise its temperature by 10 kelvin is 0.02 Cal/gK

From the question given above, the following the following data were:

Mass of metal (M) = 770 g

Heat (Q) required = 155 calories

Change in temperature (ΔT) = 10 K

The specific heat capacity of metal can be obtained as illustrated below:

155 = 770 × C × 10

155 = 7700 × C

Divide both side by 7700

C = 155 / 7700

Therefore, the specific heat capacity of metal is 0.02 Cal/gK

The kinematics and Newton's second law allow us to find the height from which the block system descends is:

             y = 6.54 m

Given parameters

To find

Newton's second law gives a relationship between the net force, the mass, and the acceleration of the body.

      ∑ F = m a

Where the bold letters indicate vectors, F is the force, m the mass and the acceleration of the body.

Kinematics studies the movement of bodies, looking for relationships between position, velocity and acceleration

              y = v₀ t + ½ a t²

In the attached we have a free body diagram of the system, let's write Newton's second law.

          T - W₁ = m₁ a

         -T + W₂ = m₂ a

Let's solve the system of equations.

          W₂ - W₁ = (m₁ + m₂) a

          a = [tex]\frac{m_2-m_1}{m_2+m_1} \ g[/tex]

Let's calculate

          a = [tex]\frac{2 -4}{ 2 +4} \ 9.8[/tex]  

          a = -3.27 m / s²

The negative sign indicates that the heaviest body is descending.

Now we can use kinematics to find the height, as the system comes out of rest the initial velocity is zero, when he reaches the ground his height is zero.

             y = y₀ + v₀ t + ½ a t²

             0= y₀ + 0  +½ a t²          

Let's calculate

             y₀ = ½ 3.27 2²

             y = 6.54 m

In conclusion, using kinematics and Newton's second law we can find the height from which the block system descends is:

             y = 6.54 m
