Acceleration = (change in speed) / (time for the change)
Change in speed = (New speed) - (old speed)
Change in speed = (0.8 m/s - 0.5 m/s) = 0.3 m/s
Time for the change = 3 seconds
Acceleration = (0.3 m/s) / (3 s)
<em>Acceleration = 0.1 m/s²</em>
(a hair more than 1 percent of 1 G.)
Answer:
Explanation:
Linear momentum of the block is conserved in the direction since the impulsive force due to impact cancels each other internally.
Using the conservation of energy to the block system considering the initial position:
Applying Sine rule:
Hence, the distance the block will slide up is 6.874mm
Answer:
The toy car
Explanation:
the real car is parked so yeah but maybe in some way technically the real car has more "momentum"
Answer:
d, Due to all reasons in a, b and c
Explanation:
All of the reasons from the choices can lead to errors in measurement. An error is an uncertainty introduced to a scientific process.
Errors can be due to the following reasons;
- It can be to a poor technician; an inexperienced scientist can introduce serious into their set up. Even when recording their observation, a dearth of experience can lead to error.
- Faulty apparatus can also lead to errors in measurement. An instrument that is poorly calibrated can also result in measurement errors.
- An inappropriate scientific method or measuring guidelines can also lead to errors in measurements.
It is easy to see the think layers in the stone. Metamorphic rock often forms layers due to being squeezed under pressure. Since it separates into think sheets,slate has been used for chalkboards roof,shingles,and pool table tops.
