5. Two friends moving towards each other are 500m apart. If they start moving towards each otherwith 10 m/s and 15 m/s then after what time they will meet?

Answer» SPEED of first friend 10m/s
speed of second friend 15m/s
total speed 25m/s
total distance 500 m
total time= distance / speed
= 500/25
= 20 sec


so they will meet after 20 second

10.

two resistance of 5 ohm and 10 ohm are connected in parallel and combination also connected with a battery of 6 volt calculate the current drawn from the cell and also the current flowing through each Resistance

Answer»

The QUESTION is TESTING you to see if you know the voltage rule for parallel resistors: Voltage remains the same across parallel resistors.

EDIT: It wasn't asked in the question but I'll ADD the current rule for parallel resistors: Current through each parallel resistor must be calculated separately with I = V/R.

Knowing the voltage rule gives you the answer you SEEK.

11.

some solids diffuse in liquids but not in gases,some solids diffuse in gases but not in liquids .why?

Answer»

This is done DUE to the process of sublimation.because during this process the SOLID converts into gas without CHANGE in liquid.

R = 7t-1 then find (a) velocity at t=1 second and acceleration at t=2 second

Answer» R = 7T - 1
Differtiating both sides with RESPECT to time
dr/dt = d(7t-1)/dt
VELOCITY = d(7t)/dt - d(1)/dt
v = 7 - 0
v = 7
Therefore velocity at any time is 7
Velocity at t=1 is 7 m/s

Acceleration = dv/dt
=d(7)/dt
=0
Therefore acceleration = 0

Therefore velocity = 7 and acceleration = 0

Prove f=mass×acceleration

Answer»

According to newton's 2ND law of MOTION
F= mv- mu/t

A body of volume 100cm³ weighs 5kgf in air.It is completely immersed in a liquid of density 1.8*10³ kg m∧-3.Find the upthrust due to liquid and weight of the body in liquid?

Answer»

Volume of BODY , V = 100 cm³ = 100 × 10^-6 m³
V = 10^-4 m³
weight of body in air , W = 5Kgf =50N [ assume , g= 10m/s²]
density of liquid , d = 1.8 × 10³ kg/m³

now, UPTHRUST due to liquid , F = Vdg
where V is the volume of body ,
d is the density of liquid ,
g is the Acceleration due to gravity.
so, F = 10^-4 × 1.8 × 10³ × 10 = 1.8 N

now, weight of body in liquid , W' = W - F
where W is weight of body in air ,
F is upthrust due to liquid .
so, W' = 50N - 1.8 N = 48.2 N

46.

An athelets runs a certain distance before taking a long jump why ?

Answer»

According to the NEWTON's LAW (o don't remember which one)
A body remains to be at rest or MOTION until an external force acts on it.
so while running, the body of an athlete is in motion, and while he jumps, his body continues to be in motion GIVING him a longer distance travelled in air.

Why valency of elements in specific group is same?Plzzzzz answer it quickly I will make him /her brainliest

Answer»

The periodic table is arranged in such a WAY that the number of shells of an ELEMENT determines its period and the number of valence electrons of an element determines its group.


So, we can conclude that same group elements have same valence elements.

So, group 1 elements have 1 valence electron

Similarly group 2 elements have 2 valence electrons and group 3 have 3 and so on upto group 7.


The number of valence electrons of elements belonging to same group is same.

So, the valency of elements belonging to same group is same.

Thus, a SPECIFIC group elements have same valency.


Hope you understand my explanation.

I also hope this must helps you.
