Satellites would be able to detect fires when they start and allow human monitors to review the information and issue warnings.
Answer: v = 2.53 m/s at E 53.1° S
Explanation:
Conservation of momentum
The 400 g object has no North-South velocity, so the initial momentum in that direction is zero. The total momentum after collision must also be zero
0 = 400(8sin35) + 650vy
vy = -2.82376... m/s
In the East direction
400(10) = 400(8cos35) + 650vx
vx = 2.121097...m/s
v = √(2.12² + 2.82²) = 3.531667... ≈ 2.53 m/s
θ = arctan(vy/vx) = arctan(-2.82/2.12) = -53.087... ≈ E53.1°S
<span>A switch running STP is classified as a backup bridge. what state is it in. The Answer is Blocking</span>
Answer:
a)5mm
b)3.3%
Explanation:
first note down the what's given
Area=
Mass of the runner=
=70kg
Fmax= 8 F (since tendon can stretch 8 times of runner's weight)
= 8 g=8 x 70 x 9.8=> 5488N
L=15cm=> 0.15m
a)
/AΔL
YAΔL=Fmax. L
ΔL=
ΔL=
=> 5mm
b) L=15cm= 150mm
Fractional change can be determined by,
(ΔL/L) *100
=
=3.33%
