Answer:
6 m/s^2
Explanation:
The average acceleration of the car is given by:
where
v is the final speed
u is the initial speed
t is the time elapsed
For the car in this problem,
v = 22 m/s
u = 4 m/s
t = 3 s
Therefore, the acceleration of the car is
Answer:
new volume = 30.513L
Explanation:
V1 =17L , P1= 2.3atm , T1=299K , T2=350K , P2 =1.5atm, V2=?
To find the new volume of the gas we will use the combined gas law.
The combined gas law combines Boyle's law, Charles law and Gay-Lussac's law. Its states that the ratio of the product of pressure and volume to temperature is equal to a constant. its expressed mathematically below.
V2 =30.513L
Answer:
K = 13.276 GJ
Explanation:
Given:
Mass of the aircraft (m) = 98,000 metric ton
Speed of the aircraft (v) = 32 knots
Kinetic energy of the aircraft (K) = ?
We know that,
1 metric ton = 1000 kg
∴ 98,000 metric ton = 98,000 × 1000 = 9.8 × 10⁷ kg
Also, 1 knot = 1 nautical mile per hour
So, 32 knots = 32 nautical miles per hour
Converting nautical miles per hour to meter per second using the following conversions, we get:
1 nautical mile = 1852 m
1 hour = 3600 s
Therefore, 1 nautical mile per hour =
So, 32 nautical miles per hour =
Therefore, the mass and speed of the aircraft are:
Now, kinetic energy is given as:
Plug in the above values and solve for 'K'. This gives,
Now, we know that, 1 GJ = 10⁹ J
Therefore, the value of 'K' in terms of GJ is given as:
K = 13.276 GJ
