You Know?

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.

Answer:

When a underground suddenly breaks along a fault it cause vibration it is called earthquake.

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.

Answer:

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 85 × 5.5

We have the final answer as

Answer:

30N is the correct answer

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

59

Explanation:

edge 2021

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.

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]

Answer:Mechanical waves, electromagnetic waves, and matter waves.

Explanation: does are the waves

Answer:

A. TRUE

B. TRUE

C. It depends on the mass of both the objects

D. TRUE

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]

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 =

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

Answer:

your answer is correct

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]
