Answer:

(a) 200.0628 N ; ( b) 4.08Kg

Explanation:

We know,

w = mg [here w= weight , m= mass , g= gravity]

now,

gravity on earth (g) =9.807 m/s²

mass of the spanner (m)=?

weight of the spanner on earth(w) = 40N

⇒ w = 40N

⇒m g =40N

⇒m = (40/g) Kg

⇒m= (40/9.807)Kg

∴m=4.08Kg

∴mass of the spanner on earth = 4.08Kg

We know,

Mass is the amount of matter in an object . So mass will remain same both on earth and jupiter.

So,

(b)The mass of the spanner on jupiter = 4.08Kg

Now,

The mass of the spanner on jupitar (m) = 4.08Kg

Gravity on jupiter (g*) = 5.g [5 times on earth]

= 5 . (9.807)m/s²

=49.035 m/s²

(a)

∴weight of the spanner on jupitar(w*) = m g*

=(4.08 x 49.035) N

=200.0628 N

Tanzania [10]

Answer: $Q=31.368\ \mu C$

Explanation:

Given

capacitance $C=30\ muF$

Resistance $R=110\ Omega$

Applied Voltage $V=4\ V$

$t=0.001\ s$

Charge on Capacitor in a R-C circuit is given by

$Q=Q_0(1-e^{\frac{-t}{RC}})$

$Q=CV(1-e^{\frac{-t}{RC}})$

$Q=30\times 10^{-6}\times 4(1-e^{\frac{-0.001}{110\times 30\times 10^{-6}}})$

$Q=120\times 10^{-6}\times 0.2614$

$Q=31.368\ \mu C$

Conservation of Momentum Practice

Yakvenalex [24]

Answer:

Before: 0 m/s

After: -4 m/s

Explanation:

Before: Since you and your beau started at rest, your beau initial velocity is 0 m/s.

After: Since we have to conserve momentum,

momentum before push = momentum after push.

The momentum before push = 0 (since you and your beau are at rest)

momentum after push = m₁v₁ + m₂v₂ were m₁ = your mass = 60 kg, v₁ = your velocity after push = 3 m/s, m₂ = beau's mass = 45 kg and v₂ = beau's velocity.

So, m₁v₁ + m₂v₂ = 0

m₁v₁ = -m₂v₂

v₂ = -m₁v₁/m₂ = -60 kg × 3 m/s ÷ 45 kg = -4 m/s

So beau moves with a velocity of 4 m/s in the opposite direction

Use the following information for question 26 and 27. A 550-g ball traveling at 8.0 m/s undergoes a sudden head-on perfectly ela

Gnoma [55]

Answer:

The speed of 250 g ball after collision is 14 m/s.

Explanation:

mass of first ball, m = 550 g = 0.55 kg

initial velocity of first ball, u = 8 m/s

mass of second ball, m' = 250 g = 0.25 kg

initial velocity of second ball, u' = - 8 m/s

Let the speed of the balls is v and v' after the collision.

Use conservation of momentum

m u + m' u' = m v + m' v'

0.55 x 8 - 0.25 x 8 = 0.55 v + 0.25 v'

0.55 v + 0.25 v' = 2.4 ..... (1)

Use the formula of coefficient of restitution,

For elastic collision, e = 1

$e =\frac{v'-v}{u - u'}\\\\1 =\frac{v'-v}{8+8}\\\\16 =v' - v...... (2)$

By solving (1) and (2)

v = - 2 m/s and v' = 14 m/s

Two stones, one with twice the mass of the other, are thrown straight up and rise to the same height h. Compare their changes in

Lady bird [3.3K]

<h2>The gravitational potential energy is double for stone with twice the mass of other stone.</h2>

Explanation:

Let mass of stone 1 be m.

Mass of stone 2 is twice the mass of stone 1.

Mass of stone 2 = 2m

We know that

Gravitational potential energy = Mass x acceleration due to gravity x Height

PE = mgh

For stone 1 ,

PE₁ = mgh

For stone 2 ,

PE₂ = 2mgh = 2 PE₁

So the gravitational potential energy is double for stone with twice the mass of other stone.
