Acceleration is a vector quantity which is defined as the rate at which an object changes its velocity

Answer:

P V = N R T     ideal gas equation

P2 / P1 = T2 / T1       where the other variables are constant

P2 = (T2 / T1) * P1 = (313 / 293) * 40 psi = 42.7 psi

The block moving at instant the spring is compressed 15cm is  √[(25m - 45)/m]

When there is no external force acting on the system, the total mechanical energy remains conserved.

K.E i = K.E f + SPE

1/2 mu² =1/2 mv² + 1/2 kx²

Substitute u = 5m/s, k =2000N.m and x =0.15m, we get the final velocity

1/2 mu² =1/2 mv² + 1/2 kx²

v =√[(25m - 45)/m]

Thus, the block moving at the instant the spring has been compressed 15 cm is √[(25m - 45)/m]

A projectile is shot with the initial speed, it follows the motion called projectile motion. The height of the cliff is 44.91 m.

The speed at the start of the motion is the initial speed.

The horizontal distance is

x = v₀ sin θ. t

Substitute 26.5 for θ, 24 for x and 8.94 m/s for x, we get the time taken to complete the journey.

t = 24/ (8.94 cos26.5) = 3 s

Maximum height reached

H = v₀²sin²θ/2g

H = (8.94)² x sin²( 26.5) /(2 x 9.8)

H =0.8118 m

The height of the cliff is obtained by the equation of motion

0.8118 - h = -1/2 gt² +v₀sinθ.t

Substitute the values, we get

h =0.8118 +1/2x9.8x (3)²

h =44.911m

Thus, the height of the cliff is 44.91 m.

Answer:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration.

Explanation:

Answer:

The correct answer is - C.  Increasing the concentration increases the reaction rate.

Explanation:

Answer:

B. Increasing the temperature increases the reaction rate.

Explanation:

The reaction time column displays how long the reaction ran for. If a reaction rate was fast then time taken for reaction to run would be slow right?

Therefore, original condition had reaction time of 10 second, but increaseing temperature lowered the time to 5 second, which must mean that reaction rate increased.

The change in friction force experienced by the car is

The friction is caused between two uneven contacting surfaces.

When car is on ice, the friction force is

f = μ N

f₁ = 0.2 x 14500 = 2900N

When the car is on dry road, the friction force is

f₂ = 0.8 x 14500 =11,600 N

The change in friction force =11600 - 2900 = 8700N

Thus, the change in friction force experienced by the car is  8700N.

Given ,

Mass of the body (m) = 200g

Amplitude (A) = 20mm

Maximum force (F) = 0.6 N

Maximum velocity (vmax) =?

We know that

Fmax = mv2max/A

or , 0.6 = 200×10-3xv2max/20×10-3

or , 0.6×20/200= v2max

or , vmax = 0.24 m/s

∴ Maximum velocity = 0.24 m/s2

The value of maximum velocity will be 0.3464 m/s². Energy or work is equal to the product of force and displacement.

The change of distance with respect to time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is m/sec.

The given data in the problem is

Mass of the body is,(m= 200g)

Amplitude is,(A  =20 mm)

Maximum force is,F= 0.6 N

To find;

Maximum velocity

Energy or work is equal to the product of force and displacement.

[tex]\rm KE = \frac{1}{2} mV_{max}^2 \\\\ \rm F_{max} \times A = \frac{1}{2} mV_{max}^2 \\\\ F_{max}= \frac{1}{2}\frac{ mV_{max}^2}{A} \\\\ 0.6= \frac{1}{2}\times \frac{ 0.2 \times V_{max}^2}{20 \times 10^{-3}} \\\\ V_{max}=0.3464 \ m/sec^2[/tex]

Hence,the value of maximum velocity will be 0.3464 m/s².
