What is the force of gravity between two objects that are 4.0 m apart? The mass of the first object is 0.25 kg and the mass of the second object is 0.65 kg

Answers

Answer:

6.77 x 10^-13 Newtons

Explanation:

using the formula [tex]F= \frac{GMm}{r^2}[/tex]

where G is the gravitation constant which is 6.673 x 10^-11 N m2/kg2

M = mass of the first object which is 0.25 kg

m = mass of the second object which is 0.65 kg

and r is the distance between the objects which is 4 metres

Plugging our values in:

[tex]F\:=\:\left(6.673x10^{-11}\right)\frac{\left(0.25\right)\left(0.65\right)}{4^2}[/tex]

F = 6.77 x 10^-13 N

A 35kg cannonball sits at rest on a flat level surface. What is the normal force exerted on the cannon ball. Use -9.8 m/s2 for acceleration due to gravity.

A. -343N

B. 44.8N

C. 25.2N

D. 343N

Answers

Answer:

a) N = 343 [N]

Explanation:

We must remember Newton's third law, which tells us that the force acting on a body is equal to the normal reaction force of equal magnitude but acting in the opposite direction.

[tex]N=m*g[/tex]

where:

m = mass = 35 [kg]

g = gravity acceleration = 9.81 [m/s²]

[tex]N = 35*9.8\\N= 343 [N][/tex]

What is the relationship between the frequency and the wavelength of a wave?

Answers

Answer: The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

12. How many grams of beryllium are needed to produce 36.0 g of hydrogen? (Assume an excess of water.)
Be(s) + 2H, O() → Be(OH)2 (aq) +H,(g)
a
4.00 g
b. 36.0 g
c. 162 g
d 324 g

Answers

Answer:

Answer is: 162 g of beryllium.

Chemical reaction: Be + 2H₂O → Be(OH)₂ + H₂.

m(H₂) = 36,0 g.

m(Be) = ?

n(H₂) = m(H₂) ÷ M(H₂)

n(H₂) = 36,0 g ÷ 2 g/mol = 18 mol.

from reaction: n(Be) : n(H₂) = 1 : 1.

n(Be) = n(H₂) = 18 mol.

m(Be) = n(Be) · M(Be).

n(Be) = 18 mol · 9 g/mol = 162 g.

Answer:

Answer is: 162 g of beryllium.

Chemical reaction: Be + 2H₂O → Be(OH)₂ + H₂.

m(H₂) = 36,0 g.

m(Be) = ?

n(H₂) = m(H₂) ÷ M(H₂)

n(H₂) = 36,0 g ÷ 2 g/mol = 18 mol.

from reaction: n(Be) : n(H₂) = 1 : 1.

n(Be) = n(H₂) = 18 mol.

m(Be) = n(Be) · M(Be).

n(Be) = 18 mol · 9 g/mol = 162 g.

Explanation:

We must remember that speed is defined as the relationship between the displacement in a given time. In this way, we can propose the following equation.

where:

v = velocity = 2 [m/s]

d = displacement [m]

2. An 873 kg dragster accelerates at a rate of 44.6 m/s during a race.
a. What is the magnitude of the net force exerted on the dragster during this time?
Known (Given):
=
Unknown:
Fnet =
Equation:
Fret=ma (or m*a)
Solution:

Answers

Answer:

38,673.9N

Explanation:

According to newton's second law:

Force = mass * acceleration

Given

Mass = 873kg

acceleration = 44.66m/s²

Magnitude of the force is expressed as;

F = ma

F = 873 * 44.6

F = 38,673.9N

Hence the magnitude of the net force exerted on the dragster during this time is 38,673.9N

N January the company produced 3,470 units using 13,880 pounds of the direct material and 2,896 direct labor-hours. During the month, the company purchased 16,900 pounds of the direct material at a cost of $14,640. The actual direct labor cost was $103,840 and the actual variable overhead cost was $47,220. The company applies variable overhead on the basis of direct labor-hours. The direct materials purchases variance is computed when the materials are purchased. The labor rate variance for January is:

Answers

Answer:

the labor rate variance is $416 favorable

Explanation:

The computation of the labor rate variance is shown below:

But before that actual labor rate is

The Actual labor rate is

= Actual direct labor cost ÷ Actual labor hours

= $103,840 ÷ 2,896

= $35.856354

Now  

labor rate variance is

= (Standard rate - Actual rate) × Actual Hours

= ($36 - $35.856354) × 2,896

= $416 Favorable

Hence, the labor rate variance is $416 favorable

Answers

Answer:

The skater has mechanical/gravitational potential energy at the two meter mark. The skater gets to two meters high on the other end of the ramp. In terms of the conservation of energy, the skater will never go higher than two meter on the other end of the the ramp because energy can be neither created nor destroyed.
