the correct answer choice woud be C. hope this helps :)
Explanation: Mountain ranges that form close to a subduction zone are likely to experience volcanic activity.
Answer:
b : 60m
Explanation:
when a plane mirror is placed horizontally on a level ground at a distance of 60m from the top of tower as shown in figure. a/c to question, The top of tower and its image in the mirror subtend an angle of 90° at the eyes. so, angle made by top of tower and horizontal line is 45° as
Answer:
turning
Explanation:
because the moment of a force is for pivots
the moment of a force can be clockwise motion and anti clockwise motion

Given:
u= 0.91 m/s
a=0.31m/s∧2
s= 0.61 m
s = ut +1/2(at∧2)
where s is the displacement of the object
u is the initial velocity
t is the time
a is the acceleration
Substituting the values
0.61=0.91×t +(0.31 ×t∧2)/2
0.61=0.91 t + 0.155 t∧2
t=0.61 secs
Consider the equation
<u>v=u +at
</u>
where v is the initial velocity
u is the initial velocity
a is the acceleration
t is the time
Substituting the values we get
v= 0.91 +(0.31×0.61)
v= 1.099 m/s
Answer
given,
initial speed of the car = 90 m/s
final speed of the car = 0 m/s
distance taken to stop = 110 m
calculating the acceleration of the car = ?
using the equation of motion
v² - u² = 2 a s
0² - 90² = 2 x a x 100
a = 40.5 m/s²
acceleration of the formula one car is equal to a = 40.5 m/s²
