Answer:

1. P_{2} = 8 x 10^{4} Pa

2. P = 1.5 x 10^{5} N/m^{2}

Explanation:

1. From Boyles' law;

P_{1}V_{1} = P_{2}V_{2}

P_{1} = 1 x 10^{5} Pa

V_{1} = 9.6 m^{3}

V_{2} = 12 m^{3}

Thus,

1 x 10^{5} x 9.6 =  P_{2} x 12

 P_{2} = \frac{100000 x 9.6}{12}

     = 80000

P_{2} = 8 x 10^{4} Pa

2. Pressure, P = ρhg

where: ρ is the density of the fluid, h is the height/ depth and g is the acceleration due to gravity (9.8 m/s^{2}).

Thus,

P = 1020 x 15 x 9.8

  = 149940

P = 1.5 x 10^{5} N/m^{2}

An object with a mass of 5kg accelerates at 2m/s2. How much force in Newtons(N) is needed to cause this to happen??
Reptile [31]

Answer: The formula of Newtons second law of motion is F=MA so therefore it would be written like this Force = Mass X Acceleration

F = 5 x 2

F = 10 N

Giving brainliest!! if you answer correctly :) (30pts)
myrzilka [38]

Answer:

mass = 4kg

Explanation:

Kinetic Energy = 1/2 x m x v²

where m = mass and v = velocity

So,

KE = 50

1/2 × m × 5² = 50

1/2 × m × 25 = 50

m = (50 x 2)/25

m = 100/25

m = 4 kg

Kali left school and traveled toward her friend's house at an average speed of 40 km/h. Matt left one hour later and traveled in
zlopas [31]

Answer:

t = 5 hr

Explanation:

Let kali moves toward east with velocity= V₁= 40 km/ h

Mat moves toward west with velocity = V₂= 50 km/hr

As Klai left one hour earlier = t₁= 1 hr

distance traveled in 1st hour = s₁ = v * t = 40 * 1 = 40 km

Remaining distance = 400 - 40 = 360 km

As they move in the opposite directions:

Relative speed= 40 + 50 = 90 km/ h

s = v * t

⇒ t = s / v

⇒ t₂ = 360 / 90

⇒ t₂ = 4 hr

Total time = t = t₁ + t₂

t = 1 hr + 4 hr

t = 5 hr
