If your brakes fail, look for something to rub against, try to pick something that will not give way.True or False?

Yanka [14]

Answer:

False

Explanation:

False

If brakes fail then we should not run against any object or wall to slow down the speed instead we should use friction forces slow down the car and shift gear to neutral to cease any acceleration.

By driving zig-zag motion friction force on the tires may stop the car after some distance.

Do not try to shut off the engine as it will lock the steering mechanism any prove fatal.

PLS ANSWER WITH EXPLANATION OR SOLUTION (WILL GIVE 50 PTS)

Fed [463]

Answer:

$\underline{ \boxed{F_m = 3.35 { \times 10}^{ - 2} N}}$

Explanation:

$since \: in \: this \: case \to \: \underline{ v }\: is \perp \: to \:\underline{ q} \\ then \: the \: magnetic \: force \: (F_m) \: is \: max = qvB \sin(90) \\ F_m = qvB \times (1) = qvB \\ hence \to \\ F_m = qvB \\ where \\ \: q = 0.75 C : v = 235m {s}^{ - 1} : B = 1.9 { \times 10}^{ - 4} T \\ therefore \to \\ F_m = 0.75 \times 235 \times 1.9 { \times 10}^{ - 4} \\ F_m = 176.25 \times 1.9 { \times 10}^{ - 4} \\ F_m = 0.0334875 = 3.35 { \times 10}^{ - 2} N \\ \boxed{F_m = 3.35 { \times 10}^{ - 2} N}$

What are the effects of overpopulation on a specific species in an ecosystem?

bagirrra123 [75]

Tere would be too many so there would be more fighting. Thye could overpopulate the world and destroy our stuff for example if it is a pig they can easily destory crops. We would all have to go hunting. There would also be less food so that is why they would start going out and destroying stuff.
