If the time of the impact in a collision is extended by 4 times ,how much does the force of impact change

Rama09 [41]

We know, I = F.Δt
As Δt is increased to 4 times, then, F would decrease to 4 times, in order to keep that impulse constant.

In short, Your force will change to 1/4th of it's initial value

Hope this helps!

20 points plz help i dont really understand how to do this

1. Calculate the equivalent resistance in the circuit :

In the given diagram, the resistors are in series connection,

So equivalent resistance = sum of resistance of both resistors.

$\large \boxed{R_{eq} =R_1 +R_2 }$

$R_{eq} = 480 + 360$

$R_{eq} = 840 \: ohms$

Therefore, Equivalent resistance = 840 ohms.

2. Calculate the current through the battery :

$\boxed{ \mathrm{current = \dfrac{potential \: \: difference}{resistance} }}$

$i = \dfrac{120}{840}$

$i = \dfrac{1}{7}$

$i = 0.142 \: Amperes$

Hence, current through the battery = 0.142 A

3. How much current is passing through each resistor :

Since the resistors are joined in series connection, the current flowing through each resistor will be equal = 0.142 Amperes.

By conservation of angular momentum

I1*ω1 = I2*ω2 -----> I1*ω1/I2 = 129*95/32 = 383 RPM <<<<<

383 rev/min * 2πrad/rev * 1min/60s = 383*2π/60 = 40.1 radians/s <<<

Why are fossils more commonly found in sedimentary rocks and not igneous rocks?

stiv31 [10]

The reason you only see fossils in sedimentary rock is that these set of rocks are formed in much lower pressure and temperature, compared to the other types of rocks like igneous rocks.
