Answer:
The horizontal component is zero.
The vertical component is
Explanation:
Given that,
The lizard climb 7m directly up on a tree.
We know that,
The horizontal component is
The vertical component is
If the lizard climb 7m directly up on a tree then,
We need to find the components
Using given data
The horizontal component of lizard is
The vertical component is
Hence, The horizontal component is zero.
The vertical component is
C because when the part gets out of the probe it would no longer stay contacted
Answer:
b. It is dropped
Explanation:
If the initial velocity is zero, the object move from rest. That happens if the object is dropped
Answer:
The acceleration of the object is
Explanation:
Given:
Initial velocity of object = 200 feet/second
Final velocity of object = 50 feet/second
Time of travel = 5 seconds
To calculate acceleration of the object we will find the rate of change of velocity with respect to time.
So, acceleration is given by:
where represents final velocity, represents initial velocity and is time of travel.
Plugging in values to evaluate acceleration.
The acceleration of the object is (Answer). The negative sign shows the object is slowing down.
Answer:
1.2 amps :)
Explanation:
A heater has a resistance of 10.0 Ω. It operates on a 12.0 V. What is the current through the resistor?
Known:
Unknown:
I = V/R
= 12.0 V / 10.0 Ω
= 1.2 amps
