The answer is the vehicle. At the precise moment of the impact in a collision, there is the release of energy when a vehicle strikes another vehicle or another object. Earlier to an impact, a vehicle and everything inside the vehicle is traveling at whatever speed the vehicle had been going. As the collision continues, the vehicle slowly loses energy. However, the vehicle occupants and any others items in the vehicle continue to move forward at the same speed as the vehicle had been traveling prior to impact.
Answer: 0.02kg
Explanation:
The quantity of heat energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since,
Q = 50 joules
Mass of iron sample = ? (let unknown value be Z)
C = 100 J/kg°C
Φ = 25°C
Then, Q = MCΦ
50J = Z x 100 J/kg°C x 25°C
50J = 2500J/kg x Z
Z = (50J/2500J/kg)
Z = 0.02kg
Thus, the mass of the iron sample is 0.02kg
Force Is A Vector That Has Both - Magnitude And Direction !
Answer:
the magnitude of A is 3.577
Explanation:
According to the question it is given that there is a magnitude of 8.0 m that added to the vector A that lies on x axis also the sum of two vectors would be third vector by considering the y axis and the magnitude is the twice of the magnitude B
The computation of the magnitude of A is shown below:
A = 3.577
Hence, the magnitude of A is 3.577
