Answers

Answer 1

Answer:

0.2g/cm³  

Explanation:

Given parameters:

Mass of the beef  = 11.6g

Volume  = 58cm³  

Unknown:

Density  = ?

Solution:

Density is the mass per unit volume of a substance.

  Density  = [tex]\frac{mass}{volume}[/tex]  

So;

  Density  = [tex]\frac{11.6}{58}[/tex]    = 0.2g/cm³

A 55-kg box rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.30. A 140-N force is applied to the box. What is the frictional force on the box?

Answers

Answer:

161.7N

Explanation:

Given parameters:

Mass of the box  = 55kg

Coefficient of friction  = 0.3

Applied force  = 140N

Unknown:

Frictional force on the box = ?

Solution:

The frictional force on the box is a force that opposes the motion of the box.

To find the value of this force;

        Fr  = u m g

u is the coefficient of static friction

m is the mass

g is the acceleration due to gravity

 So;

     Fr  = 0.3 x 55 x 9.8  = 161.7N

HELPPPPP MEEEEE PLEASE I NEED TO SUBMIT IN LESS THAN 10 MINSS

Answers

Answer:

X = 2146.05 m

Explanation:

We need to understand first what is the value we need to calculate here. In this case, we want to know how far from the starting point the package should be released. This is the distance.

We also know that the plane is flying a certain height with an specific speed. And the distance we need to calculate is the distance in X with the following expression:

X = Vt   (1)

However we do not know the time that this distance is covered. This time can be determined because we know the height of the plain. This time is referred to the time of flight. And the time of flight can be calculated with the following expression:

t = √2h/g   (2)

Where g is gravity acceleration which is 9.8 m/s². Replacing the data into the expression we have:

t = √(2*2500)/9.8

t = 22.59 s

Now replacing into (1) we have:

X = 95 * 22.59

X = 2146.05 m

This is the distance where the package should be released.

of the following states of motion, the one which requires balanced forces is:
A: a decrease in speed in a straight line
B: an increase in speed in a straight line
C: constant speed in a straight line
D: a change in the direction of the motion

Answers

I believe it would be D a change in direction of motion

A balanced force is required for a change in the direction of the motion.

What is a force?

According to Newton's second law of motion, the force applied to a body is directly proportional to the product of mass and acceleration of the body.

Balanced forces

Balanced forces are those that are opposite in direction and equal in size. When forces are balanced there is no change in direction.

Thus, when there is change in direction, a balance force can be applied to cancel the change in direction of motion.

Which situations will NOT increase the reactions rate of most chemical reactions?

A) an increase in temperature

B) grind up the solute to increase surface area before mixing

C) by increasing the pressure in which the reaction takes place


D) decreasing the concentrations of the substances in the reaction

Answers

Answer:

D

Explanation:

Increasing temperature or pressure some times make the condition favorable to the reaction. Similarly increasing surface area  of reacting mixture also helps to increase the reaction rate.

What is reaction rate ?

The rate of  a reaction is the rate of decrease in concentration of reactant or the rate of increase in concentration of the products. The rate of a reaction depends on several factors such as temperature, pressure, surface area etc.

Fir an endothermic reaction, as the temperature increases, reaction rate increases. Similarly, as the pressure increases, the reaction in which the number of moles of gaseous reactants is higher than that in products, rate increases.

The concentration of reactants must be sufficient for the reaction and decreasing the concentration of reactants does not favor an increase in reaction rate. Hence, option D is correct.

Three sharks are located at the vertices of an equilateral triangle whose side equals LL. They all start moving simultaneously with a constant speed vv, with the first shark heading constantly toward the second, the second toward the third, and the third toward the first. How soon will the sharks converge at one point

Answers

Answer:

They will never meet.

Explanation:

Given that three sharks are located at the vertices of an equilateral triangle whose side equals LL. They all start moving simultaneously with a constant speed vv, with the first shark heading constantly toward the second, the second toward the third, and the third toward the first. How soon will the sharks converge at one point ?

Since the three sharks are located at the vertices of an equilateral triangle whose side equals, and the first shark is moving toward the second, the second is moving toward the third, and the third shark is moving toward the first, the movement of the three shark will form a circular motion.

Since the three sharks are moving at a constant speed, the three sharks will never meet because the distances between them are also the same.

The three sharks will therefore continue to move till infinity.

7. An object with a weight of 19.6 N moves with a constant velocity of 20.0 m/s. A net
force of 6.00 N is applied to the object in the direction of its motion for 4.00 seconds.
What is the final momentum of the object?

Answers

Answer:

118.4kgm/s

Explanation:

Given parameters:

Weight of object  = 19.6N

          mass of object  = 19.6/9.8   = 2kg

Constant velocity  = 20m/s

Force applied  = 6N

Time taken  = 4s

Unknown:

Final momentum of the object  = ?

Solution:

To solve this problem, we use Newton's second law of motion;

           Ft  = m (v  - u)

F is the force applied

t is the time taken

m is the mass

v is the initial velocity

u is the time taken

           Ft  = mv  - mu

mv is the final momentum;

       So;

     Final momentum  = Ft + mu

 Final momentum  = (19.6 x 4) + (2 x 20) = 118.4kgm/s

The first egg is thrown at a wall and breaks because it has no time to decelerate and it breaks.

While, when a second egg is thrown at wall with same velocity and collides with a bed sheet, it does not break because it get more time to decelerate  or collide with the wall.  It reduces the amount of force exerted on the egg and it does not break.

Equation of motion description is v=20+2t.How big is the initial speed,acceleration?

Answers

Answer:

the initial velocity is 20 m/s   and  the acceleration is 2 m/s²

Explanation:

Given equation of motion, v = 20 + 2t

If V represents the final velocity of the object, then the initial velocity and acceleration of the object is calculated as follows;

From first kinematic equation;

v = u + at

where;

v is the final velocity

u is the initial velocity

a is the acceleration

t is time of motion

If we compare  (v = u + at)   to     (v = 20 + 2t)

then, u = 20    and  

         a = 2

Therefore, the initial velocity is 20 m/s   and  the acceleration is 2 m/s²
