It means that if the mass of a mass is increased by some factor, and nothing else changes, then the weight of that mass increases by exactly the same factor.
Answer:
3.13cm/s²
Explanation:
Given
Initial velocity u = 3.5cm/s
Final velocity v = 8.2cm/s
Time t = 1.5secs
Required
Acceleration of the cart a
To get that, we will use the equation of motion
v = u+at
Substitute the given parameters
8.2 = 3.5+1.5a
1.5a = 8.2-3.5
1.5a = 4.7
a = 4.7/1.5
a = 3.13cm/s²
Hence the acceleration to the cart is 3.13cm/s²
Answer:
(a) Girl acceleration = 0.15 m/s², (b) Sled acceleration = 0.93 m/s²
Explanation:
Given:
M1=Mass of girl = 43 Kg
M2= mass of Sled = 7.1 Kg
Force F= 6.6 N
To Find (a) a1 = girl acceleration (b) a2 = sled acceleration
Solution:
F1 = F2 = F (Newton's 3rd Law)
F=ma (Newton's 2nd Law)
(a) F = M1a1
⇒a1 = F/M1 = 6.6 N / 43 Kg = 0.15 m/s²
(b) a2 = F / M2 = 6.6 N / 7.1 Kg = 0.93 m/s²
Answer:
OPTION A is the correct answer
Voltage = joules/coulomb
1 coulomb = 6.25 x 10^18 electrons
8.5 x 10^18 electrons = 1.36 coulombs
136 joules / 1.36 coulombs = 100 volts
===================================
The statement regarding the ball is false. Any object that's not hanging from something
or resting on something is accelerating downward on account of gravity. No matter what
direction you throw the ball, or how hard, its acceleration is 9.8 meters per second^2
directed downward, from the instant it leaves your hand until it hits the ground.
