Answer:
600Kg
Explanation:
Force= mass × acceleration
mass= 1500/2.5
600kg
The mass of the rocket will be 600 kg.In the International System of Units (SI), the kilogram is the unit of mass.
What is mass?Mass is a numerical measure of inertia, which is a basic feature of all matter. It is, in effect, a body of matter's resistance to a change in speed or position caused by the application of a force.
In the International System of Units (SI), the kilogram is the unit of mass.
The given data in the problem is;
The net constant force is, F= 1500 N
The acceleration is,a=2. 5 m/s²
The mass of the rocket is,m=?
[tex]\rm F= mass \times acceleration \\\\ m = \frac{F}{a} \\\\ m= \frac{1500}{2.5}\\\\ m = 600 \ kg[/tex]
Hence the mass of the rocket will be 600 kg.

Knowing the direction of heat flow, explain why if you leave a hot bowl of soup out in the open on the countertop, it eventually gets cold. Where is the heat going?
The heat will flow towards the air surrounding the soup bowl and towards the countertop below the bowl.
Where does the heat go?We know that when two bodies of different temperatures there will be a flow of heat between the objects, from the hotter one to the colder one.
In this case, we have the bowl of soup as the hot object, and the ambient (the countertop, the air surrounding the bowl, etc) itself will be the cooler object.
Then the heat will flow towards the air surrounding the soup bowl and towards the countertop below the bowl.

Answer:
I for a rod about its center is I = M L^2 / 12

Is it possible For dogs to be gray
Answer:
Yes, it is possible for dogs to be grey
Explanation:
Whippets are gray and they are a type of dog
Answer: Like humans, dogs tend to go gray as part of their natural aging process.
Explanation: Just like us, humans, dogs tend to go gray as part of their natural aging process. And just like us, as dogs get older, the pigment cells responsible for color (specifically, melanin) stop being produced; this causes the strands to come out at a lighter shade, like gray or white.

A coffee filter of mass 1.3 grams dropped from a height of 3 m reaches the ground with a speed of 0.5 m/s. How much kinetic energy Kair did the air molecules gain from the falling coffee filter
Answer: .0380575J
Explanation:
The coffee filter originally only had potential energy, which can be found by:
PE = m * g * h → PE = .0013 * 9.8 * 3 = .03822 J
*Note the mass must be in kg!!!
All of this energy should be converted to kinetic energy, but the air molecules take some of the energy; the energy they gain can be found by finding how much energy the filter has at the bottom of its fall, and subtracting this from the original energy to see how much was lost;
All of the energy at the bottom equals kinetic energy, which can be found by:
KE = 1/2 * m * v^2 → KE = 1/2 * .0013 * .5^2 = .0001625 J
Thus, the air gained .03822 - .0001625 = .0380575J :)
A 50 kg object moving at 15 m/s collides with another 50 kg object moving in the same direction at 10 m/s. If the collision is inelastic, what is the final velocity of the two objects after they combine?
Answer:
12.5 m/s
Explanation:
By conservation of momentum, we have that:
[tex]\displaystyle m_1v_1 + m_2v_2 = m_1v_1' + m_2v_2'[/tex]
Because the two objects combine after collision, they will have the same velocity:
[tex]\displaystyle m_1v_1 + m_2v_2 = (m_1+m_2)v_f[/tex]
Substitute and solve for final velocity:
[tex]\displaystyle \begin{aligned} (50 \text{ kg})(15\text{ m/s}) + (50\text{ kg})(10\text{ m/s}) & = ((50+50)\text{ kg})v_f \\ \\ v_f & = 12.5\text{ m/s}\end{aligned}[/tex]
In conclusion, the final velocity of the system will be 12.5 m/s.
Complete the mechanism for the given decarboxylation by adding any missing atoms, bonds, charges, nonbonding electrons, and curved arrows
The decarboxylation reaction involves the removal and replacement of a carboxyl group with hydrogen.
What is a decarboxylation reaction?A decarboxylation reaction is one in which the carboxyl group in a carboxylic acid is replaced with hydrogen.
In living organisms, decarboxylation reactions are catalyzed by enzymes called decarboxylases or carboxy-lyases.
The decarboxylation of beta-carbonyl esters proceeds through a cyclic transition state giving an enol intermediate which then tautomerises to the carbonyl.
Therefore, a decarboxylation reaction involves the removal and replacement of a carboxyl group with hydrogen.

(a) before the submarines pass each other, sub b quickly turns around and speeds up to 12. 4 m/s. What is the change in frequency noticed by observers on sub b? (enter you answer to one decimal place. )
The change in frequency noticed by observers on sub b is : 2.66 Hz before the submarines pass each other.
Given data:
New speed of Sub b ( Vb ) = 12.4 m/s
F₁ = 1416.44 Hz
Frequency of sonar wave ( Fₐ ) = 1400 Hz
Speed of sound in water ( V ) = 1533 m/s
Speed of submarine A ( Va ) = 8.4 m/s
Determine the change in frequency observed on sub BThe change in frequency can be calculated using the formula below
F₁' = Fₐ ( V + Vb / V - Vₐ )
= 1400 ( 1533 + 12.4 / 1533 - 8.4 )
= 1400 ( 1545.4 / 1524.6 )
= 1419.1 Hz
Final step : determine the change in frequency
ΔF = F₁' - F₁
= 1419.1 - 1416.44
= 2.66 Hz.
Hence we can conclude that The change in frequency noticed by observers on sub b is : 2.66 Hz.

The frequency is the number of waves that travel through a particular place in one unit of time. The change in frequency noticed by observers on sub b is 2.66 Hz.
What is the frequency?The frequency is the number of waves that travel through a particular place in one unit of time. It may also be described as the number of cycles or vibrations experienced by a body in periodic motion in one unit of time.
Given that the new speed of the sub B is 12.4 m//sec, while the frequency of the submarine is 1416.44 Hz. The frequency of the sonar wave of submarine A is 1400 Hz. Also, the speed of sound in water, V is 1533 m/sec, and the speed of submarine A is 8.4 m/s.
Now, the frequency of the sub B after the speed is increased will be equal to,
[tex]F_1' = F_a \times \dfrac{(V+V_b)}{(V-V_a)}[/tex]
[tex]\rm = 1400 \times \dfrac{(1533+12.4)}{(1533-8.4)}\\\\=1400 \times \dfrac{1545.4}{1524.6}\\\\=1419.1\ Hz[/tex]
Further, the change in frequency noticed by observers on sub b,
[tex]\rm \triangle F = F_1'-F_1 = 1419.1-1416.44 = 2.66\ Hz[/tex]
Hence, the change in frequency noticed by observers on sub b is 2.66 Hz.

A piece of cheese is placed on a vertical spring of negligible mass and a force constant k = 2300 N/m that is compressed by a distance of 18.0 cm. How much elastic potential energy is stored in this system? (Answer in J)
Answer:
E = 1/2 K x^2 (1/2 *F * x * x)
E = 2300 / 2 N/m * (.18 m)^2 = 37.3 Joules
The quantity of elastic potential energy that is currently stored in the system is equal to 37.26 Joules (J).
We may use the formula for elastic potential energy to compute the amount of elastic potential energy that is stored in the system, which is as follows:
PE, or Elastic Potential Energy, is 0.5 times k times x squared.
where k represents the constant force that the spring exerts and x represents the amount of compression that the spring experiences.
Given:
The spring has a force constant of 2300 Newton-meters (k).
The spring was compressed (x) by 18.0 centimetres, which is equivalent to 0.18 metres when measured in metres.
To finish, enter the values into the formula as follows:
PE = 0.5 × 2300 N/m × (0.18 m)² PE = 0.5 × 2300 N/m × 0.0324 m² PE = 37.26 J
37.26 Joules (J) is the amount of elastic potential energy that is stored in the system.

A 4000 kg freight car moving at 3 km/hr collides and couples with an 8000 kg freight car which is initially at rest. the final speed of the combined cars is
Answer: 0.28 m/s (1 km/hr)
Explanation:
This is an inelastic conservation of momentum question.
First, convert the speed to m/s: 3 km/hr (1000m/1km)(1hr/3600s) = .83 m/s
Then, Momentum before = Momentum after;
Momentum before = m1v1 + m2v2 = 4000(.83) + 8000(0)
Momentum after: (m1 + m2)v3 → (4000 + 8000)v3
Set these equal: 4000(.83) = 12000v3 and solve to get: v3=.28 m/s :)
