That would be false.
Straight angle= 180 degrees
Obtuse angle= Above 90, and lower than 180
Acute angle= Below 90
Hope this helps! (:

ANSWER AND EXPLANATION:

--------------------------------------------------------------------------------------------------------------

INFORMATION

--------------------------------------------------------------------------------------------------------------

Frequency - 50Hz. Which means that the time period of the wave if 1/50 = 0.02 sec. Here we are going to check the average voltage for the time interval of 0.01sec. If the interval lies between π/2 to 3π/2. the average voltage will be zero. In all the other cases it will not be zero

--------------------------------------------------------------------------------------------------------------

ANSWER

--------------------------------------------------------------------------------------------------------------

So, the answer will be <u><em>may be zero. </em></u>

A crate rests on the flatbed of a truck that is initially traveling at 15 m/s on a level road. The driver applies the brakes and

lina2011 [118]

Answer:0.3

Explanation:

Given

velocity of car=15 m/s

truck brought to halt in a distance of 38 m

We know

$v^2-u^2=2as$

Final velocity (v)=0

$0-(15)^2=2(a)(38)$

$a=\frac{-225}{76}$

$a=-2.96 m/s^2$ (deceleration)

Therefore minimum coefficient of friction \mu will be

$\mu \times g=a$

$\mu =\frac{a}{g}$

$\mu =\frac{2.96}{9.8}=0.302$

An unwary football player collides with a padded goalpost while running at a velocity of 5.70 m/s and comes to a full stop after

ollegr [7]

The relationship between the initial velocity, final velociy, distance, and deceleration can be expressed in the following equation.

2(a)(0.270 m) = 0² - (5.70 m/s)²

The value of a (which is the deceleration) is 0.06 m/s². Thus, the answer is that the deceleration value is approximately 0.06 m/s².
