How can temperature influence the rate chemical reaction between an acid and a base that will make our rocket defy gravity and launch upward?
Answer:
Explanation:
Generally, an increase in temperature increases the rate of a chemical reaction. Consequently, when the temperature of a reaction is raised, the molecules present in the reaction interact faster by colliding with one another and surpassing the effective collision of such reaction to bring about a high reaction rate. Similarly, in the case of the rocket launch, the same process occurs as the temperature increase will cause an increase in the reaction rate leading the hydrogen from the acid to react explosively with the oxygen from the base to form water - this makes the rocket defy gravity and launch upward.

What is the acceleration of an object with a mass of 367 kg when a net force of 183 N is applied to it
Answer:
[tex]0.5m/s^{2}[/tex]
Explanation:
F= m x a
a= [tex]\frac{F}{m}[/tex] = [tex]\frac{183 N}{367 kg}[/tex] = [tex]\frac{0.4986 N}{kg}[/tex] = [tex]\frac{0.4986 kg*m/s^{2} }{kg}[/tex] = [tex]0.5 m/s^{2}[/tex]

calculate the height from from which a body is released from rest if its velocity just before hitting the ground is30m\s
Answer:
height = 45 m
Explanation:
Initial velocity = 0 m/s
Final velocity = 30 m/s
Acceleration due to gravity = +10m/s^2 ( because ball is going down )
Using the eqn of motion
[tex] {v}^{2} - {u}^{2} = 2gh[/tex]
where v= final velocity ; u = initial velocity ; g = acceleration due to gravity ; h = height
So,
[tex] {30}^{2} - {0}^{2} = 2 \times 10 \times h[/tex]
[tex] = > 20h = 900[/tex]
[tex] = > h = \frac{900}{20} = 45[/tex]
1. A plane flying horizontally at an altitude of 490 meters and having a velocity of 250 meters per second east, drops a supply packet to a work crew on the ground. It falls freely without a parachute. [Assume no wind and negligible air resistance.] A. Calculate the time required for the packet to hit the ground. (25 pts)
Answer:
t = 10 s
Explanation:
Given :
Altitude, h = 490 m
Initial velocity of a plane, u = 250 m/s
To find :
The time required for the packet to hit the ground. When it hits the ground its velocity will be 0. Let t is the required time. It can be calculated as follows :
[tex]t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2\times 490}{9.8}} \\\\t=10\ s[/tex]
So, it will take 10 s to reach the ground.

If a tennis ball has a velocity of 18 m/s and a momentum of 1.06 kg • m/s, what is the mass of the tennis ball in grams? Round the answer to two significant figures.
Answer:
58 g
Explanation:
Momentum = mass* velocity
P=mv
P= 1.06 kg*m/s
M=?
V=18 m/s
1.06 kg*m/s=m(18m/s)
M=0.058 kg
0.058kg = 58 g

A car accelerates from rest at a rate of 3 m/s² for 4 seconds. How far did the car travel?
PLEASE help fasttt
Answer:
24m
Explanation:
Given parameters:
Initial velocity = 0m/s
Acceleration = 3m/s²
Time = 4s
Unknown:
Distance covered = ?
Solution:
To solve this problem, we apply the right motion equation:
S = ut + [tex]\frac{1}{2}[/tex]at²
S is the distance
u is the initial velocity
t is the time taken
a is the acceleration;
S = (0 x 4) + [tex]\frac{1}{2}[/tex] x 3 x 4²
S = 24m
How many seconds are there in a calendar year,given that a calendar year has 365.24 days in it?
Answer:
31556736
Explanation:
Since there are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year, then you multiply all of those.
60*60*24*365.24 =
31556736

A transformer has 1000 turns on the primary coil.
The voltage applied to the primary coil is 230V a.c,
How many turns are on the secondary coil if the output
voltage is 46 V a.c.?
A)20 B)200 C)2000 D4000 E)8000
Answer:
200
Explanation:
Given parameters:
Number of turns in primary coil = 1000 turns
Primary voltage = 230V
Secondary voltage = 46V
Unknown:
Number of turns in secondary coil = ?
Solution:
To solve this problem, we have to use the expression for solving problems related with transformers;
[tex]\frac{Vs}{Ns}[/tex] = [tex]\frac{Vp}{Np}[/tex]
Vs is the secondary voltage
Ns is the number of secondary turns
Vp is the primary voltage
Np is the number of primary turns
Now insert the parameters and solve;
[tex]\frac{46}{Ns}[/tex] = [tex]\frac{230}{1000}[/tex]
46 x 1000 = 230Ns
Ns = 200
among 1 litre boiling water and red hot glowing nail which one has more amount of heat and why
Answer: The Water
Explanation:
The boiling litre of water has more volume and so has more heated molecules per cubic metre so it will have a higher amount of heat than the glowing nail.
To practically test this, put the glowing nail into a litre of cold water and record the final temperature when the nail has cooled down. Repeat this with the boiling litre of water. You will notice a higher final temperature with the boiling water indicating that it had more heat.
The gradual temperature change from one season to the next is due to what? view attachment
find the amount and the compound interest on rupees 10000 for 2 years at 5% per annum compounded annually
Compound interest:
[tex]a = p( 1 + \frac{r}{n} ) { }^{nt} [/tex]
a = final amount
p = principal amount
r = rate of interest
t = time
n = no. of compounding periods per year
p = 10000
r = 5% = 5/100 = 0.05
t = 2
n = 1
[tex]a = 10000(1 + \frac{0.05}{1} ) {}^{2 \times 1} [/tex]
[tex]a = 10000(1 + 0.05) {}^{2} [/tex]
[tex]a = 10000(1.05) {}^{2} [/tex]
[tex]a = 10000(1.1025)[/tex]
[tex]a = 11025[/tex]
