The problem seems to be incomplete because there is no question. However, from the problem description, the logical question is to find he acceleration needed by the jet to land on the airplane carrier. The working equation would be:
2ad = v₂² - v₁²
Since the jet stops, v₂ = 0. Substituting the values:
2(a)(95 m) = 0² - [(240 km/h)(1000 m/1 km)(1h/3600 s)]²
Solving for a,
<em>a = -23.39 m/s² (the negative sign indicates that the jet is decelerating)</em>
Answer:
The bus
Explanation:
a = (v-u)/t
Where
a = acceleration
v = final velocity
u = initial velocity
t = time taken
For truck to get its acceleration,
a = (18-0)/5.5 = 3.27 ms⁻²
For bus to get its acceleration,
a = (24-0)/6 = 4 ms⁻²
As 4 > 3.27 bus has a greater acceleration.
Answer:
D
Explanation:
The least of the conditions that can result in fossilization would be <u>when an organism is a prey to several species.</u>
Fossils are remains or traces of organisms that have been geological preserved and a prey is an organism that is often hunted and serves as food to bigger organisms. <em>When an organism is eaten, the probability of it becoming a fossil becomes low. Unless such an organism is usually partially eaten by predators, there would not be any remains, let alone being fossilized.</em>
The correct option is D.
If the battery is reversed and reconnected to the bulb, the bulb will glow <span>with the same brightness. The correct option among all the options that are given in the question is the third option or the penultimate option. I hope that this is the answer that you were looking for and it has actually come to your help.</span>
The bullet will strike the target placed in 324.0 m in the East in 0.45 seconds.
<u>Explanation:</u>
As we all know the epic relation between distance, speed and time; we cam easily estimate the time in which an object can reach to the destination or target.
As here in this case, we know the distance of the target and the velocity of a bullet exerted from a rifle given as follows,
Distance of the Target from the rifle edge = 324.0 m
Velocity of bullet exerted from the rifle = 720 m/s
Since we know that,
or
We can simply implement all the values in the formula and get the results i.e the time required by the bullet to hit the target. Since both the values are in S.I units measures, we don't need to change or convert any of them. Hence,
Therefore, the bullet will hit the target in 0.45 seconds.
