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
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.

How are scientists able to predict when and where the next eclipse will occur?
Answer:
When the Earth and sun are perfectly lined up, then it will happen. They can tell when it's going to happen.
Explanation:
This is why it only happens in some places. Some days it's not sunny out, so it's not going to happen.

An object with mass 30 kg travelling as speed of 11 m/s receives an impulse of
240 kg m/s. What is the final velocity of the object?
Answer:
V₂ = 19 [m/s]
Explanation:
The final linear momentum will be equal to the sum of the initial momentum plus the momentum received. By means of the following equation, we can determine the final momentum.
[tex]m_{1}*v_{1} + IMP_{1-2} = m_{2}*v_{2}[/tex]
where:
m₁ = m₂ = mass = 30 [kg]
v₁ = velocity = 11 [m/s]
IMP₁-₂ = 240 [kg*m/s]
v₂ = final velocity [m/s]
[tex](30*11) + 240 = 30*V_{2}\\330 + 240 = 30*V_{2}\\v_{2}=19 [m/s][/tex]
The final velocity of the object is 19 m/s
The impulse is given by:
Impulse = m(v - u)
where m is the mass, v is the final velocity and u is the initial velocity.
Given that impulse = 240 kgm/s, u = 11 m/s, m = 30 kg. Hence:
Impulse = m(v - u)
240 = 30(v - 11)
8 = v - 11
v = 19 m/s
The final velocity of the object is 19 m/s

What is the acceleration of the box?
Answer:
a=4,32m/s^2
Explanation:
Fnet = F1 - F2
= 12-1.2
= 10.8N
m=2.5kg
Fnet =ma
10.8=2.5a then divide both sides by 2.5 to get acceleration

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]
A football player with a mass of 100 kg from runs from rest towards his opponent and hits him with a force of 500 Newtons 5 seconds later. What was his momentum before impact?
Answer:
2500kgm/s
Explanation:
Change in momentum is equal to impulse, numerically.
Ft=m( v-u)
But he begins from rest so u= 0
Then
Ft= mv
500(5)=mv
2500= mv
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]

Complete question
A cannon with a muzzle velocity of 500. meters per second fires a cannonball at an angle of 30.° above the horizontal. What is the vertical component of the cannonball's velocity as it leaves the cannon?
A 0.0 m/s
B 250. m/s
C 433 m/s
D 500. m/s
Answer:
The correct option is C
Explanation:
From the question we are told that
The velocity is [tex]v = 500 \ m/s[/tex]
The angle is [tex]\theta = 30^o[/tex]
Generally the vertical component of the canon ball is mathematically represented as
[tex]v_y = v * cos (30 )[/tex]
=> [tex]v_y = 500 * cos (30 )[/tex]
=> [tex]v_y = 433 \ m/s[/tex]
Answer:
250. m/s
Explanation:
It is vertical component so you do: 500mSin(30°) = 250m/s

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.

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

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.
