Answer:
64°
Explanation:
The triangle is an isosceles triangles (both legs are equal to the radius of the circle), so that means the base angles are the same.
Angles of a triangle add up to 180°, so:
128 + 2x = 180
2x = 52
x = 26
∠1 is complementary to the base angle, so:
∠1 = 90 − 26
∠1 = 64
Answer:
Gravity is a constant quantity
Explanation:
We know that m = 5 kg
a = 3.0 m/s^2
g = 9.8 (since not written, lets assume it's an international standard)
T - mg = ma
T = mg + ma
T = (5 . 9.8) + (5 . 3 )
T = 49 + 15
T = 64 N

Answer:
The work done is 
Explanation:
Work is defined as the product of force and distance moved in the direction of application of force.

Given Data
distance S= 230m
force F= 140 N
Mass of car m= 1140 kg
Applying the formula for work done we have

The work done by pushing the car for a distance of
is
