Answer:
Given that
u = 13 m/s
h= 23 m
a) horizontally
We know that acceleration due top gravity is in vertical direction.
v²=u'²+ 2 g h ( u'= 0 )
v² = 2 x 9.81 x 23
v= 21.24 m/s ( vertical direction)
In the horizontal direction
u = 13 m/s
The resultant velocity
V²=v²+u²
V²=21.24²+13²
V= 24.91 m/s
(b) vertically straight up
u= 13 m/s
v²=u²+ 2 g h
v²=13²+ 2 x 9.81 x 23
v= 24.91 m./s
c)vertically straight down.
u= 13 m/s
v²=u²+ 2 g h
v²=13²+ 2 x 9.81 x 23
v= 24.91 m./s
Answer:
there are 22 massive, positively charged, fundamental particles in the element's nucleus. Given this, the element is unquestionably titanium.
<span>The correct answer is B. Inverted image. This is because of all the lenses and light refractions and what not. The same things happens with our eyes except our brains fix the inverted image automatically. Since there are no brains in a projector, you have to fix it on your own by putting it in reverse.</span>
Answer:
the simple machines in this list are the saw, hammer, screwdriver, ruler, and the pulley system.
Explanation:
SAW: place saw on wood then push and pull to shave away at the wood.
HAMMER: aim for nail and hit really hard without hitting your hand.
SCREWDRIVER: place screw bit in screw socket and twist.
RULER: place against object and look at the mesurement on the numbers.
PULLEY: attach an object on one end of the pulley rope and pull on the other end to raise the end with the attached object.
When two negatively charged objects are brought near each other, a repulsive force is produced. When two positively charged objects are brought near each other, a similar repulsive force is produced. When a negatively charged object is brought near a positively charged object, an attractive force is produced.
Hope this will help u mate :)
