Answer:
= 8.46 × 10³N
Explanation:
W = 1.3 × 10⁴
v₁ = 0
v (friction) = 95km/h = 26.4 m/s
t = 5s
f = 1450N
mass of body = W / g
=1.3 × 10⁴ / 9.8
=1327 kg
v(friction) = v + at
substitute in eqn 1
26.4 = 5a
a = 5.28 m/s
Force Net = F₁ + F₂ + F₃ = ma
F (engine) = ma + F
= 1327 (5.28) + 1450
= 8.46 × 10³N
Answer:
B
Explanation:
nothing to do with black holes creating star or related
Answer:
The magnitude of the resultant decreases from A+B to A-B
Explanation:
The magnitude of the resultant of two vectors is given by
where
A is the magnitude of the first vector
B is the magnitude of the second vector
is the angle between the directions of the two vectors
In the formula, A and B are constant, so the behaviour depends only on the function . The value of are:
- 1 (maximum) when the angle is 0, so the magnitude of the resultant in this case is
- then it decreases, until it becomes 0 when the angle is 90 degrees, where the magnitude of the resultant is
- then it becomes negative, and continues to decrease, until it reaches a value of -1 when the angle is 180 degrees, and the magnitude of the resultant is
Answer:
11 m/s
Explanation:
Impulse equals change in momentum.
I = Δ(mv)
Since mass isn't changing:
I = m Δv
16 Ns = (2.0 kg) (v - 3.0 m/s)
v = 11 m/s
Answer:
Hello your question is incomplete hence I will give you a general answer as regards to tectonic plates sliding past each other in a sideways direction
answer : The Transform boundary is been demonstrated by the students when sliding tectonic plates past each other in sideways directions
Explanation:
The event that can be demonstrated by the students using blocks to represent tectonic plates and sliding the clocks past each other in sideways direction is Transform Boundary of the tectonic plates
